What is this fibrobeton? Fibrobeton - application, characteristics and technology composition of fibrobetone with polypropylene fiber
Fibrobeton is one of the most common building materials. This is a concrete, which is reinforced by dispersed fibers (fibrami). Fibrobeton has a higher impact strength, cutting strength and tensile, waterproof, frost resistance, fire resistance and cavitation resistance.
Fibrobeton and its application
To date, steel and glass fibers are sufficiently used for fiber reinforcement of concrete (fibrobetones), thereby expanding the use of synthetic fibers. In addition to them, basalt, carbon and other fibers also apply. Fibrobeton reaches maximum efficiency when all components are selected in the correct combination of their properties, that is, the properties of fibrobeton as composite material depend on the properties of its components forming it. In some sense, the main components in this case will be steel or non-metallic fiber. 
Steel fibrous reinforcement in this case can be called the most effective, even considering its relative cost. The elastic modulus of this material is greater than that of concrete, approximately 5 times, thereby, with the necessary anchoring in concrete, the strength and fib will be fully used, and Fiber will create the greatest contribution to the work of the composite at the stages of the crack formation and their endings.
If we are talking about Steel Fiber, then questions to ensure its ankill in concrete are solved more difficult, for example, for synthetic fibra. Making steel fibra occurs mainly by the following methods. Use cutting from thin wire or steel too thin sheet; steel melt exhaust (extrusion); Milling of special slabs. Fiber can have a different cross section, it can be rectangular, round, etc. Dimensions range from 0.2 mm to 1.6 mm and in length from 5 mm to 160 mm. Tensile strength is from 400 to 1100 MPa.
Fiber concrete compared to traditional concrete is beneficial, since it has higher indicators. We are talking about higher tensile strength and slice, shock and fatigue strength; Frost resistance and waterproof fibrobeton are also higher; Perfectly resists abrasion and cavitation. Fibrobeton in terms of the work of destruction is capable of almost 20 times above concrete. Thus, it provides this material the opportunity to actively use in building structures, as well as with repairs.
The main characteristic of fibrobeton usually distinguishes its tensile strength. It can be considered as a direct characteristic of the material and as an indirect, which shows the material resistance to other influences, including durability. Another important characteristic is the impact strength (or viscosity of destruction). In fibrobeton, the value of this indicator is 3-5 times the value of ordinary concrete. Designs can be carried out using only fibrobeton, and can with combined reinforcement, which uses fiber and rod, or wire fittings. Domestic experience, however,, as well as foreign, shows that fibrobeton is a universal material and its use becomes more and wide in the field of construction.
Technology production fibrobeton
The basis of this material includes an ordinary concrete and fiber additive (fiber) - fittings, fiberglass or polymer additives. From the name of the fiber used for the reinforcement of concrete, the name of the fibrobeton (glassfibobeton, steelfibetone, etc.) occurs. In concrete, fiber is added at the stage of production of concrete mix, through traditional mixing, spraying, "premixing". If it is necessary to obtain the directional location of the fibers - apply a magnet. It performs the function of the reinforcing component, contributing to improving the quality of concrete and increasing its deformability, crack resistance, frost resistance and waterproofability. Additional advantages of fibrobeton are fire resistance and reduced weight in comparison with traditionally reinforced concrete. Due to this, the process of mounting structures from fibrobeton is largely facilitated. In terms of exploitation, the fibrobeton exceeds concrete 15-20 times.
Production of fibrobeton 
Fibrobeton with synthetic fibers is technologically manufactured by premixing or spraying (pneumon spray). At the factories, it is often used to premixing method (pre-preparation of fibrobeton mixture). At the first stages of the technological cycle into a concrete fine-grained mixture, a chopped fiber is introduced followed by stirring. From the received premix-solution, a construction structure is manufactured using methods of vibration absorption, roller molding, roller pressing, extrusion. The second method is used directly on construction sites. Spraying is carried out under pressure using special equipment through a pistol-repulsive. This is synchronously served chopped fiber and fine-grained concrete solution. Then they mix in a pistol - spider. During the application of a solution by means of spraying, simultaneous processing of large areas is possible.
Fibrobetones are used in monolithic and prefabricated structures that function for alternate loads. For the manufacture of fibrobeton floors, a concrete modifier is used, consisting of a powder on an organic-mineral base (microsillis, hardening regulators and superplasticizers). This base is added steel fiber, alkaline glass fiber or polypropylene and basalt fiber. Such varieties of fibers allow its introduction and subsequent mixing is much easier and more efficient. After time, the deformation module remains unchanged, so fibrobetonic floors made of these composite materials do not have a shrinkage, and on the contrary, becoming more stable and stronger to damage.
Fibrobeton
Fibrobeton is a type of cement concrete, in which fiber or fiber fiber is quite uniformly distributed as a reinforcing material.
Under the collective name "Fiber", the segments of thin steel wire, nail production, etc., metal fibers, glass, polymers (mainly propylene) are implied. Fiber is added to concrete at the stage of production of concrete mix, performing the function of the reinforcing component, and helps to improve the quality of concrete, increasing its crack resistance, deformability, waterproof and frost resistance. The additional advantage of fibrobeton is its reduced weight compared to traditionally reinforced concrete, which facilitates the installation of structures from fibrobeton.
Fibrobetones are used in prefabricated and monolithic structures that work for alternate loads. The most important characteristic of fibrobetone - tensile strength - is not only a direct characteristic of the material, but also indirectly, and reflects its resistance to other effects. Another important characteristic of fibrobeton is its durability. In terms of the work of the destruction, the fibrobeton can exceed 15-20 times to exceed concrete.
The technology of production of fibrobeton Polypropylene fiber is falling asleep into a solution or a concrete mixer before water is added to a dry mixture. The stirring time is from 4 to 6 minutes. If you need to increase the plasticity of the solution or concrete, then you must add a plasticizer. Polypropylene fiber is fully compatible with all additives into a solution or concrete. Dosage: 0.6-0.9kg / m3 Packaging: in packages of 0.6-0.9 kg. Fibrobeton, production Fibrobeton technology is one of the most common building materials.

Fibrobeton has a higher impact strength, cutting strength and tensile, waterproof, frost resistance, fire resistance and cavitation resistance. 
The listed advantages in the aggregate ensure high efficiency of using this material, therefore, products from fibrobeton, such as fibrobetonic blocks, panels and stoves are used in building structures. For example, fibrobeton floors are more resistant to increased operational loads than ordinary concrete floors.
The technological production of fibrobeton is a conventional mixture of sand, cement, large aggregate, water and a certain amount of dispersed fibers (fibers). Fiber, in turn, is made from various materials.
Fibrobeton - Building Material of the Contemporary World
Every year it becomes becoming increasingly popular. It is due to this with an optimal combination of its operational, technical and decorative characteristics.
Fibrobeton: Technology and Properties
Fibrobetone is called a mixture of concrete of a fine-grained structure with fiber, that is, the reinforcing filler. Reinforced glass fibobeton fragments of steel, glass or synthetic fibers. Their diameter varies from 0.2 to 1.0 mm, and the length is from 5 to 150 mm. 
Fiber is distributed in the mixture evenly in thickness, in an arbitrary direction. Such a solution provides fibrobetone excellent performance: a combination of plasticity with a high bending strength and stretching strength, excellent shock viscosity, resistance to crack formation.
Compared to the concoction of the traditional composition, the fibrobeton is much longer, is famous for increased wear resistance and resistance to negative atmospheric and biochemical influences. The complex of these properties significantly reduces the mass of architectural structures by reducing their thickness.
Fibrobeton floors and their advantages
Only appearing in the construction market, Fibrobeton immediately declared itself as a unique material. Its technical characteristics are much higher than the indicators of ordinary concrete:
fatigue and impact strength is much higher, and the wear resistance rate increased twice;
Higher crack resistance and waterproofability, as well as decent strength characteristics on the slice and stretching;
very strong viscosity (more than 10 times);
Improved frost resistance and, as a result, high resistance to temperature drops.
Production
The main secret of such unique properties is special polymer additives (binder and emulsion). The use of fibers, continuous or in the form of segments, gave the name of the material itself - fibre (translated as "fiber"). For reinforcement, a threads of metal, organic or mineral are introduced into the starting line. It is they who attach its unusual properties to the material.
Our company works only on modern European technologies. This allows us to guarantee an excellent result in the production of fibrobeton (or fibrized concrete) and fibro-tie. Our concrete with the addition of Fiber meets all the stated characteristics, which is ensured by using special polymers with the addition of a minimum of water. 
Features Application
Another difference in fibrobeton from the usual lies in the fact that due to three-dimensional hardening, the volume of metal reinforcement is significantly reduced. As a result, the costs are not only reduced, but also, for example, the coating becomes more maintainable at higher durability.
Main applications:
erection of bank safes and storages;
construction of bridges, dam, gateways, dam;
Atomization is the storage and disposal of radioactive materials in the construction of branches for reactors;
repair and strengthening underground structures;
Laying the runway.
Fibrobeton floors are equally relevant. In civil construction, they were appreciated for the strength and a smaller fragility. High performance indicators are achieved by our specialists through the use of high-quality cement (M500), high-tech polymer additives and special fractionated sand. As a result, even industrial floors from the fibrobeton, to which special requirements impose, do not form cracks, do not give shrink, but only gain strength over the years.
Fibrobeton floors depending on operational requirements may be different due to the grade of the cement used (M150-500). When filling the floor, the maximum difference of 2 m is only 2 mm. This allows you to drastically reduce the costs of subsequent convective and finishing work. When using fibrobeton, the floors are poured very quickly, especially when using pneumatic equipment (it is possible to fill up to 60 floors).
Our experts recommend pouring floors from fibrobeton in the following rooms:
industrial and industrial workshops;
all types of warehouse premises;
Automaster, garages, parking lots, parking, including multi-storey;
Exhibition and trading halls;
All types of hangars are airfield, cargo;
Office buildings and premises.
In addition to all the unique properties of fibrobeton, we offer not only significantly increase the physicochemical characteristics of the floors, such as wear resistance, chemical stability, but also increase their decorative indicators. If necessary, the floor is additionally reinforced. For this, special polymer compositions are used, which have protective properties - high-filled and bulk coatings, paint, impregnation.
In the construction industry, progressive technologies are being introduced and new materials are used. One of them is fibrobeton. Do not everyone know that this is a composite, differing from concrete with increased strength. The material contains special fibers, which are proportional to the concrete array, performing the function of the reinforcement. The use of fiber standard sizes made from metal or synthetic materials, significantly increases the strength characteristics. We will figure it out what fibrobeton is. Let us dwell on the properties of the material, manufacturing technology.
What is fibrobeton
When the question is what fibrobeton is, many find it difficult to give the correct answer. What it is? The material is a kind of traditional concrete, reinforced by adding fibra to the concrete mixture. For concrete composition, a reduced grain is characterized, as well as a uniform concentration in an array of various types of reinforcing elements:
- metal filler in the form of steel wire, which can have a different configuration and dimensions;
- synthetic fiber made from basalt fiber, glass filaments, asbestos, polyamide filler or acrylic.
Ensuring increased strength characteristics is achieved by introducing into metal fibers. Their diameter does not exceed half a million, and the length of the elements is from 1 to 5 cm. Steel wire is the most popular variety of filler. At the same time, the popularity of glass fibers and various polypropylene-based fillers is growing.
The construction materials market offer a new material - fibrobetonThe saturation of the concrete massif by filler improves the performance of the composite:
- strength properties;
- resistance to the effects of stretching effort;
- resistance to crack formation.
The technology of manufacturing building material allows you to simultaneously use various types of fibra:
- viscose fiber;
- nylon materials;
- cotton threads.
They increase the effectiveness of reinforcement, make it possible to achieve new characteristics without increasing production costs. The type of fibers used and their concentration affect concrete strength. In the construction industry, fibrobeton with labeling B25 is distributed. Increased safety margin is achieved by mixing steel wire with glass fibers.
Operating properties of material
Choosing a composite to solve special tasks in the construction sector is important to understand what fibrobeton is, which properties are characteristic of it. Elevated strength characteristics of composite concrete provide the possibility of building buildings from it that have increased stability with a reduced thick wall thickness. Specialists are confident that it reduces the volume of expenditures on the construction of the object. Provisted in practice formulation is used in the manufacture of concrete composite. The type of fiber used affects the operational properties.
These fibers perform the role of fittings, which is used to increase the strength of the concrete solution. The main characteristics of the composite concrete:
- the ability of the array to maintain the integrity under the influence of significant tensile loads;
- neutrality to the effects of aggressive substances, resistance to the effects of natural factors;
- frost resistance while maintaining the structure of the array with multiple and sharp fluctuations in temperature;
- resistance to intense heating caused by the effect of high temperature and open fire;
- preservation of the source volume of the array, after a set of hardness does not cause shrinkage;
- resistance to abrasive wear, abrasion, cracking, exposure to torque;
- moisture resistance due to a peculiar structure, which makes it difficult to penetrate moisture in the composite;
- increased plasticity of the concrete array, increased strength to the effects of shock loads.
Thanks to the specified properties, the material is used to solve a wide range of tasks in the construction industry.
Application area
Introduction to the concrete of various types of fibra allows you to change the properties of a material that can be used to solve various tasks.

- small-sized buildings.
More often applies viscose and cotton, the area of \u200b\u200buse of which is limited.
Pros and cons of fibrobeton
Fibrobeton is pretty new and promising building material. It is quite natural that not all developers have ideas what fibrobeton is. When planning it to use it for construction, it is useful to learn about the advantages and weaknesses of the fibrovolocon composite. The material reinforced with steel wire or synthetic threads is distinguished by increased operational characteristics.
In practice, this concrete gained great popularity due to the low fragility Consider the main advantages of the reinforced composite:
- reducing the level of costs for construction of construction work. When strengthening concrete, fibrovolocks disappears the need to use steel grids, reinforcement frames, which reduces labor intensity, reduces the duration of construction work;
- increased strength characteristics of products that are not cracking. Square resistance is associated with a uniform location of fibra in a concrete array. With a standard enhancement of concrete, reinforcement is problematic to achieve similar strength;
- resistance to sharp temperature fluctuations. Moisture cannot penetrate the reinforced fiber concrete. It retains the integrity of the array with a sharp cooling and further thawing;
- fire safety. Reinforced fiber-fiber composites perceive the effect of increased temperature and open fire without violating the structure of the array and formation of cracks;
- small weight. Light fibrobeton blocks are easy to deliver to the construction site. The laying is carried out by an accelerated pace, which allows you to quickly enter the object into operation;
- reducing the need for building materials. It is associated with the addition of reinforced fiber filler into the mixture. The increased strength of the array allows to reduce the thickness of the walls, while maintaining their stability;
- increased resource operation. The enhanced composite exceeds the standard durability concrete, while maintaining the performance characteristics for a long time.
Against the background of many advantages of material, the drawback seems insignificant. Minus - an enlarged price of fibrobeton. Carrying out the production of fibrobeton, it has to acquire expensive raw materials, carry extra costs. However, as a result of increased costs, the material acquires unique performance properties, mechanical strength and durability.
Fibrobeton has many positive properties Production of fibrobeton - technology, composition and recipe
Technology providing fibrobeton production has its own characteristics. Its effectiveness depends on a number of factors:
- selection of certain types of fibers depending on the required operational properties of the composite;
- uniform mixing of ingredients and the introduction of modifiers to ensure a homogeneous structure of the array;
- the features of the applied formulation, including the simultaneous use of various types of fibra.
It is important to properly prepare a composite composition using proven methods:
- introduction Fibrovolocone into a dry mixture of sand and cement with subsequent mixing of ingredients and the addition of water. The difference of the method is simplicity, as well as the absence of the need to attract additional labor;
- adding fibers fibers into the finished mixture of cement, water and sand. The method allows you to increase the strength characteristics of the composite, reduce production cycle.
The manufacturing process requires the use of concrete mixer and crusher The following factors affect the strength and properties of the concrete composite:
- composition of materials used;
- properly selected recipe;
- compliance with the technological process.
Depending on the required properties of the composite, the concentration of entered fibrovolocone changes. The proportion of fibers in the total volume varies from 0.5 kg to 20 kg, depending on their type. The most common fibrobeton brands contain up to 2 kg fibra. Evaluation of the quality of raw materials is produced by the laboratory method.
It includes:
- input control of materials used;
- checking the humidity of the synthetic filler.
The use of high-quality raw materials improves fibra adhesion, has a positive effect on concrete strength. Technology allows in emergency conditions to independently prepare reinforced fibrobetonic composition. This requires a concrete mixer and a crusher for chopping filler.
Let's sum up
After examining what fibrobeton is, it can be concluded that the reinforced fiber composite is a promising building material. It has a complex of indisputable advantages, allows you to solve many serious tasks in the construction industry. The unique properties of reinforced concrete appreciated professional builders and private developers. Characteristics of a composite reinforced with metal wire or synthetic fiber, allow it to compete to compete with standard brands of concrete.
What is this fibrobeton?
Requirements for the strength of structures contributed to the emergence of a new direction of the construction industry. There was a need for the use of composite materials with a uniformly distributed fiber reinforcement in the array. Fibrobeton differs from traditionally used concrete with special fibers that perform the role of fittings.
The use of metallic and synthetic reinforcing elements of the same length, cross sections significantly increases the strength of the concrete array used in the construction of the object. The effect is achieved due to compensation for the deficiencies of the traditional composition, which was distinguished by a reduced resistance to the effects of stretching effort, increased fragility.
The production of fibrobeton has a lot in common with the manufacture of concrete composition, includes the stage of preparation of ingredients with further mixing. The specifics of the technology increases the strength of the fibrobeton, which the main indicators exceeds concrete.
In this article, consider what fibrobeton is. Let us dwell in detail on the composition, characteristics, areas of application, advantages and disadvantages, technology of manufacturing a concrete composite.
The construction materials market offer a new material - fibrobeton
Features
Do you know what fibrobeton is what its features are? The material is a type of concrete, in the array of which there is a fiber. The concrete composition is characterized by a reduced graininess, uniform distribution of the following filler types:
- metal elements produced from steel wire, different sizes, configuration;
- synthetic reinforcement from basalt, glass, acrylic, asbestos, polyamide.
According to the degree of popularity, steel fibers are leading, made of the same wire fragments with a length of 10-50 mm, with a diameter of up to 0.5 mm. Increased characteristics ensures the composite the introduction of fiberglass. The popularity of polypropylene fillers is growing.
The introduction of various fibers makes it possible to improve the following properties of the material:
- Strength characteristics.
- Stability for cracks.
Builders are combined and simultaneously with steel fiber are introduced into an array of cotton threads, viscose, nylon, which enhances the effect of reinforcement and gives the material a complex of additional properties, reduces the cost of manufacture.
Properties of concrete depend primarily from the construction system used in production
The composition and concentration of fibra introduced into concrete determines the strength characteristics of the array. Popular in the construction of fibrobetones classified from B20 to B25. Improving the strength characteristics of the array ensures the simultaneous administration of a metal fiber with fiberglass filler.
Distinctive characteristics
Understanding what fibrobeton is, and what is its characteristics, you can choose composite to perform the construction tasks. The use of composite material allows you to build construction objects with high strength with a reduced wall thickness. Builders confirm that this reduces the costs associated with the construction of an object.
The formulation used in the manufacture of concrete, the fiber type used determines the operational characteristics of the array, the distinguishing properties of which are:
- the ability to maintain strength under the influence of tearing efforts;
- resistance to atmospheric factors, aggressive reagents;
- the ability to perceive the temperature differences associated with multiple freezing and thawing cycles;
- resistance to the effects of direct heating, elevated temperature, which contributes to an increase in the fire strength of structures;
His most notable qualities - long service life, density and resistance to wear
- increased elastic characteristics;
- preservation of the initial volume that allows you to avoid a unwanted shrinkage;
- resistance to the effects of mechanical abrasive efforts, crack formation;
- the ability to counteract the penetration of water deep into the array;
- increased plasticity coefficient, significant impact strength.
The positive characteristics complex provides the possibility of using the material in various fields.
Usal scope
The scope of the reinforced fiber composite differs depending on the features of the filler.
Enhanced steel fiber composite applied to the structure:
- Railway sleepers, bases of buildings, bridge coatings, waveness.
- Transport tunnels and floors capable of withstanding considerable effort.
- Paving, road surface, base of airfields.
- Decorative tiles, borders.
- Monolithic structures, buildings frames.
- Underground drains of highways, special communication wells, hydraulic structures, water treatment designs.
It allows you to get durable and relatively light architectural elements of any configuration.
As you know, the stone works well on compression, stretching resistance ensures the reinforcement frame. But the steel is located only in places of the largest estimated stretch, and in cases where the strength is necessary throughout the volume, the device of reinforcement rods becomes very expensive. Solve the problem is called fibrobeton - material with fibrous reinforcement.
Structure
Fibrobeton is a special kind of building material, characterized by high strength. Which includes:
- Cement;
- Peeled sand;
- Fibers fibers;
- Plasticizers;
- Water.
In contrast to the classic concrete solution, this does not add a large aggregate, instead the role of binding hardensors play fibers fibers. These can be materials of different origin:
- Metal fiber - steel chips. With it, concrete is obtained especially strong on the gap, stretching, prevents the formation of cracks and a significant shrinkage when hardening and drying the solution. The sizes of chips are determined according to the calculations of the structures, since the aggregator is the main component that makes over all loads and compensating them. In the need for concrete with a high carrier capacity of the edge of the chips, multiple anchors are formed performing the role of a rigid frame.
- Non-metallic fiber is most often part of the fibrobeton. This is a fiber of different origin (fiberglass, polypropylene, polyamide, acrylic, viscose, nylon, asbestos, carbon, basalt, carbon).
For the most responsible goals, metallic fiber is used, for non-loaded - polypropylene and fiberglass. Durable steel fiber can be replaced by more expensive basalt, but this option is rarely taken in mind high cost. Polymer and glass fibers are available at the price and optimal specifications.
Application of fibrobeton
Concrete with reinforcing fibers is widely used in the construction of industrial facilities, especially responsible facilities and public places:
- Road coating;
- Laying of the take-off stripes of airfields;
- Massive foundations for heavy objects;
- Durable floor in industrial workshops and warehouses;
- Sidewalks;
- Monolithic construction of houses, tunnels;
- Strengthening embankments;
- Special purpose objects: drainage mines, sewer wells, cleaning tanks;
- Bases of pools, etc.
Separate products from fibrobeton:
- Noise shields along the tracks;
- Road borders;
- Paving slabs;
- Benches;
- Fences;
- Visors, etc.
Fiber reinforced concrete is used in cases where the framework of the frame is inappropriate in terms of financial, material and labor costs. For example, the road tile reinforces is much more complicated than to introduce reinforcing fiber and simply pour concrete into the form. The same principle works with supporting structures - plates or monolithic walls in tunnels, embankment supports: the load on them is evenly accepted throughout the area, therefore any part of the product should be equally strong, which is not easy to achieve with classical reinforcement frames.
Fibrobetones, tinted by pigment, serve as the basis for creating decorative panels for finishing facades, landscape decoration, fountain cladding and other designs. Products give different shapes, relief and texture.
Specifications
For each type of filler, there is its own recipe for the preparation of the solution, respectively, concrete differs in all characteristics. The composition and characteristics of fibrobeton GOST are not regulated. According to SP 52-104-2006, the material must meet the requirements of GOST 26633-91.
For each type of material there will be their own indicators:
- For fiber from polypropylene density 0.9 g / cm3, the elastic module reaches 8000 MPa, lengthening to a gap to 25%;
- For basalt density of 2.6-2.7 g / cm3, the elastic module is up to 11,000 MPa, tensile strength up to 3200 MPa, lengthening to a gap to 3.6 MPa;
- For steel density of 7.8 g / cm3, the modulus of elasticity up to 210000 (!) MPa, and tensile strength of 3150 MPa.
As can be seen, the technical characteristics of fibrobeton differ slightly (with the exception of individual parameters, but they must be considered when choosing a fiber). We present the main parameters of fiberglass-based concrete:
All concrete on reinforced fiber differ in high frost resistance and waterproof.
Advantages and disadvantages
Fibrobeton - a unique material, superioring a regular stone for a number of qualities:
- Simplified method of reinforcement by the method of kneading components;
- Consumption of concrete decreases due to the introduction of fibers from 20% of the total volume;
- Stone strength across the whole volume increases;
- Increases viscosity and disappointment of the solution into the form;
- Good adhesive qualities;
- Increase in waterproof;
- Reducing the mass of the product and structures;
- Increased service life.
With the right selection of fibers and their characteristics, its high cost will remain its high cost, which is easily compensated by the durability of the stone and the lack of need for repair.
Fibrobeton do it yourself
This high-quality fibrobeton can be manufactured only at a preliminary calculation factory. For each type of fibra, different recipes are used, the kneading time is maintained, which is not easy at home. To independently prepare the solution, you should create a standard mixture of cement, sand and plasticizer, add fiber to them. The proportion is determined individually: 1 m3 will be needed from 300 grams. up to 25% dry fiber from total. To reduce the material, you can use a mixture of expensive and cheap fibers.
In private housekeeping, concrete stone reinforced fibers are used for a solid foundation device. It is much easier to mount, without using a separate frame of reinforcement rods, but the main condition must be fulfilled - the material must be calculated in advance in the design bureau.
Panels from fibrobeton can be made independently and bind them the facade of the house, making shields for the fence - it is much cheaper than buying ready or reinforce ordinary concrete.
Fiber for concrete - its types and expenses
The one who faced capital construction, probably heard that to improve the quality of carrier facilities to a solution, a fiber for concrete is added.
General characteristics
So, basalt or any other fiber that is added to the concrete significantly improves the strength and other qualitative indicators of the solution, increasing the service life of the finished carrier structure. Thanks to this component, the stressed material acquires special fire resistance and it takes better effects of high temperature.
The additive consists of a plurality of fine fibers interconnected. The scope of application of fiber fiber is not limited to concrete mixtures. It is used in the manufacture of foam concrete blocks, gypsum products and constructions from reinforced concrete.
Basic components additive
In order to obtain a qualitative reinforcing component, the following basis can be applied:
- polypropylene
- basalt
- steel
- glass
- metal.
For mixing composition, it does not need a separate technique, and the whole process is performed using concrete mixer. The average consumption of the material is 0.3 - 1.2 kg per m³.
Dignity
To better understand the principle of operation of the fiber additive, it is necessary to study its properties. Fibrovolok is used to reinforce concrete. Thus, when adding a component, a solid connection is formed into the composition, which helps increase the stability of the fill to mechanical effects.
Strengthening tie
For example, a metal mesh strengthens the screed in a certain part of it, and the fibers at the expense of its structure are evenly distributed in the mixture, thereby forming a strong base throughout its area.
Due to high adhesion, the construction mixture is uniform, without lumen and lumps.
The frozen surface, exposed to active exploitation, becomes more stable before abrasion, and concrete acquires tensile strength at the places of bends.
Prevention of defects
Polypropylene, steel or basalt fibers helps to avoid the formation of cracks, eliminates the formation of deforming sites and bundles of the structure of concrete.
Using such a component, the flooded structures acquire frost resistance, so that it is possible to minimize the negative effect of jumps of temperature indicators, and the material retains its integral structure.
Improving adhesion and water resistance
Concrete, which contains basalt impurity, is better adhere to other materials and increases its water resistance due to blocking cement capillaries.
To further compact the particles of the filler, it is recommended to use vibrating instruments. This significantly affects the strength of the finished design and eliminates its separation into separate layers.
Efficiency and anti-corrosion properties
It is also important that the fiber flow per 1 m³ can be increased, however, the price of such a solution will be much less than if the reinforcement was carried out using a special metal mesh. In addition, the fibers of the fastening component are not corrosion.
Scope of application
Professional builders note that a micronmaking additive can be mixed in any mortar compositions that are prepared on the basis of cement. It is most advisable to use it if the design may be subjected to cracking due to its shrinkage or other mechanical impacts projected on this object.
It also makes sense to strengthen the foundation and tie of the floor, which are poured with their own hands, since these surfaces must withstand an increased load.
Types of additives
As it became clear from the foregoing material, the firming component can be made from various bases. Now you will get acquainted in more detail with each of the types of fibrovolok.
Steel
Fiber steel fiber is most often used in the production of constructions from concrete, paving slabs, cast fences and cement monuments. It is added to the solution when pouring forms for fountains, balustrades and various massive decorative elements of the outer architecture.
Polypropylene
Polypropylene fiber is considered the most common component that enhances the building mixtures. Its popularity is explained by the available price and decent operational indicators.
From cement solutions with such an additive, foam concrete and aerated concrete blocks, roadside borders, fender panels, etc. are produced.
Basalt
Basalt Fiber, like polypropylene, gives strength to blocks with a porous structure, and is also often used when creating gypsum items.
In this case, the fiber length may differ, so its flow is adjusted individually, and the finished products will have different properties.
Fiberglass
Fiber from fiberglass in concrete is added to give it a plasticity. It has a little weight and architects are likely to work with it, which are often working on bulk, curved decor objects. The solution with the addition of fiberglass can often be found at restoration sites and when repairing architectural monuments.
Expendable norms
In the production of concrete products or during construction work, the fiber consumption may differ slightly. This is due to various areas of application of finished elements and structures, as well as varying degrees of loads on their surface. Below are the expenditure standards according to which high-quality construction mixtures are prepared:
- different types of concrete with a porous structure (polystyrene polystone, foam concrete) - 0.6 - 0.9 kg / m³
- shrews based on cement and sand, paving slabs, small architectural forms - 1.8 - 2.7 kg / m³
- concrete for parking and highways - 1.0 - 1.5 kg / m³
- tamble gypsum products - 0.4 - 0.8 kg / m³
- dry construction and plastering mixtures - 0.6 - 0.9 kg / m³
- artificial decorative stone, facade facing and other gypsum products - 0.4 - 0.8 kg / m³.
Mixing methods
Basalt or any other fiber is added to concrete in various ways, and its consumption is controlled in each individual case according to the above scheme. In enterprises strictly followed the technological process and prepare mixtures according to GOST.
A customer solution that is delivered to the place of unloading in automotive concrete mixers is enriched with fibers while filling the mixer by the building mass, and its homogeneous distribution occurs directly during transportation. For those who plan to combine the solution with their own hands, the following information will be useful.
Adding polypropylene
The polypropylene fibrous component is mixed with dry materials (cement, sand, crushed stone) with a concrete mixer, and then water is added.
The process is repeated, if necessary, pour into the mass of chemical additives, and finally mix up to complete readiness. If polyethylene fiber is used, the mixture time is increased by 15%.
Introduction Basalt
Basalt base is introduced into the solution, filled with water, while the mixer does not stop. As in the case of polypropylene material, time consumption will be increased by 15% compared to the receipt of ordinary concrete.
In order to prepare a fibrous component for concrete on its own, a special crushing machine will be required, which grinds the source material (metal, propylene, basalt, etc.) to the desired size.
Floor screed with fiber
Application in the construction work of cement solutions is always associated with a number of problems. In the initial period there are plastic shrinkage and sedimentation, then a decrease in freezing or thawing resistance is reduced, the likelihood of rapid abrasion, the penetration of moisture, chemicals, the appearance of cracks increases. In the fight against negative manifestations, the use of polypropylene fibrovolock has effective assistance. Today it is the most effective type of reinforcing materials that are actively used in different fields of industrial activity.
Fibrovolok - what is it?
The basis of production is artificial material polypropylene. The length of its fibers is 3-18 mm, the diameter is about 20 microns. Fiber has low electrical conductivity, an oil agent is applied to its surface, which improves the penetration of the material into the construction mixture.
Briefly about properties and qualities
Polypropylene fiber is designed to reinforce the screed. The advantage of additives to the cement solution give it a mass of positive characteristics:
- strength and durability
- minimum soar time
- resistance to high and low temperatures, the effects of salting-anti-icing
- reducing water permeability
- resistance to abrasion and mechanical effects
- lack of likely separation, chips, shrinking cracks
The list of obvious advantages in aggregate with low price contributes to the constant increase in the popularity of fibrovolock.
In contrast to a steel fine grid for reinforcement, polypropylene is evenly distributed in the solution, penetrating into each individual particle. In addition, the use of fibrovolock increases the ductility of the screed.
Unique material practically does not have drawbacks. The only warning for those who decided to buy reinforcing fiber: Always pay attention to the certification of goods. Elected-quality raw materials over time manifests itself with low quality and selection of chemicals damage to health.
Features of the solution with Fiber
It has absolute compatibility with all the well-known additives for concrete. To prepare a high-quality solution in which all particles are uniformly mixed with each other, it is necessary to introduce polypropylene in small portions. Part of the material is first mixed with a dry mixture, and then diluted with water.
The volume of fibrovolock consumption has a direct impact on the quality of the screed. To facilitate construction work, it is enough to introduce only 300 g per cube of the finished solution. 600 g significantly increase the strength of concrete coating. 800-900 g allow you to achieve maximum result.
Consumption per m2 of high strength screed with a layer thickness of 50 mm is obtained 40-45 g, which in the monetary equivalent is 8-9 rubles.
Polypropylene yarns
Semi-drying floor screed with fibrovolock is the most common type of application in construction and repair work. In addition, polypropylene is used:
- in the manufacture of foam blocks, polystyrene bonts, refractory products, mortar, stamped concrete
- for filling gallery, piles, foundation, road surfaces
- during the construction of hydraulic structures, underground car parks, bridges, high-rise buildings, agricultural buildings, transport and cable tunnels.
The uniform distribution of fiber fiber throughout the solution provides its reinforcement and a change in the binding properties. This process reliably prevents the emergence of structural problems, inevitably arising when using fine-wired wire mesh in floors and screeds.
How to make a screed with fibrovolok do it yourself
Before the finish finish of the floor, it is necessary to completely align its surface. To get a smooth durable plane, use a semi-dry solution from sand and cement with the addition of polypropylene yarns.
The technological process of creating a screed includes several stages.
1. Preparation of the foundation.
The surface of the floor is carefully examined for the presence of cracks, recesses, drops. The identified disadvantages are eliminated by putty. The surface of the floor is cleaned of garbage, wash and dried.
2. Laying levels.
Along the horizontal floor, measurements make measurements and make the appropriate marks on the walls. You can use beacons from wooden bars, bricks or self-tapping screws with plastic plugs that are fixed on the floor with concrete solution.
3. Preparation of the mixture.
The solution includes portland cement and sand in a 1: 3 ratio. The volume of fibrovolock is determined depending on the requirements for the screed - from 300 to 900 g / m 3. The dry mixture is bred by water to the desired consistency. The whole procedure takes only a few minutes.
4. Laying thermal insulation.
The process of insulation is necessary only for a tie of a warm floor with fibrovolock. It helps to protect the accommodation from possible heat loss. The device of the usual floor does not require the cost of thermal insulation.
5. Concreting platform.
The prepared surface is poured with a thick solution with a thickness of about 30-50 mm. Alignment of screeds are produced using Rake Rules. To the formation of the next layer (if necessary), it is proceed only after the complete frozen of the previous one.
6. Alignment of the surface.
Pull the frozen tie with a grinding device. It not only aligns the surface well, but also contributes to her strengthening. Be proceed to the grout process no earlier than 15-20 minutes after the end of the fill.
Upon completion of all works, the screed must be given time to correctly. To protect the floor from the draft, it is recommended to cover with a polyethylene film. In order to prevent the cutting of the screed (for example, in the heat), the floor must be periodically moistened with a pulverizer.
After twelve hours, the frozen sex can be walking. And after 4-5 days, we boldly begin to lay the flooring.
Fiberglass price for screed
Packing raw materials produced into polypropylene bags of 18 kg with an attachment of 20 packets of 900 g. Depending on the purpose of the fiber, the fiber is produced with long, 12, and 18 mm long. According to the reviews of Fiber for a 12 mm tie - the optimal option for the house. There are raw materials of Chinese and domestic producers.
The final value of the fiber fiber influences the total order and type of payment. To try the quality of the material in practice, it is enough to buy one bag. Retail price of minimum purchases in Moscow is 220-240 per kilogram. Accordingly, the bag of fibrovolock will cost 3 960 - 4,320 rubles. When ordering a large batch of goods, the bag can cost 3 240 - 3,420.
