Arbolit do it yourself. Garage from arbolite blocks about typical projects of arbite houses

The monolithic arbolit is among the most economical building materials used for more than 50 years in different countries for low-rise buildings. Economical construction from "Opilk concrete", as it is called, respectively, the composition will be in demand at all times, especially when erecting secondary simplicity of industrial workshops or for private country house-building. In the monolithic walls, the arbolite mass is poured into the prepared formwork, and for the traditional construction of the house, the mixture of concrete and sawdust is formed in the form of blocks.

Properties and composition of arbolit

The advantage of the material is the minimum cost, low thermal conductivity, simplicity of manufacturing technology and composition of arbolit. Brick blocks made of a mixture of sawdust and concrete with some impurities are also available and reliable, they are easy to make with their own hands right in the country area, which will give additional savings. Its minimum thermal conductivity makes it in demand even in a cold climate. Molds for filling the prepared mixture is easy to do on their own, taking into account the desired size, and if necessary, the material is well sustained.

Like foam concrete, the opilk concrete is classified as building material from a group of light concrete. He is like an artificial stone made on the basis of woodworking waste - these are chips, fine chips and sawdust. Arbolit photo - varieties of material use in construction.

Today, the arbolit form in the form of plates, blocks, panels and monolithic walls. The standard edition of the arbolite of the material is the outer blocks of 20x30x50 cm and small panels, and partitions and seals are made from blocks 20x20x50 cm. For thermal insulation, the ready-made panels 120x230x20 (28) are used. At the same time, this standard is recommended, but not mandatory, manufacturers often pour blocks Arbolite Other sizes. The diameter and form of internal voids also varies, as well as the composition of the material. According to GOST, arbolite blocks have an inner coating with a concrete-lime solution that impedes the effects of moisture.

Depending on the climatic zone and natural conditions, other dry plant components are often added to the layouts. Such brick manufacturing techniques are known in antiquity, but the most widely used a mixture of straw and clay, and today, experimenters for creating economical building materials make focus on a mixture of concrete with industrial production waste.

In the post-war time, in the period of active Soviet construction, sawdust blocks found ubiquitous use, thanks to affordability and efficiency. In addition to the monolithic arbolit, the wood mixture with concrete was flooded in the form of a hollow brick. In this case, arbolit sizes can have both standard and arbitrary, it is important that they are comfortable for laying.

Abroad, similar domestic building materials are popular:

woodstone,
dryna Pan
durisole, etc.

Today, arbolit is used for the construction:

seasplets in the construction of industrial buildings;
garages;
cozpostrok;
country houses;
warehouse premises;
dacha settlements;
model cottage construction.

In homes of small floors, the arbolit is used to build not only the inner walls, but also outdoor, requiring facing decoration, for example, siding or "wild stone". Carrier walls and minor saint are cast from arbolita, also made of small hollow blocks make light designs for fences or partitions. In addition, in the cold climatic zone, it is successfully used for an additional second layer when insulating outdoor stone walls, that is, as thermal insulation - arbolit video.

The density of thermal insulation and structural blocks - in the range of 400-850 kg / cubic meters.

The thermal conductivity of arbolite is 0.08 W / m-0.17 W / m, that is, higher than that of foam concrete, ceramzite concrete and all types of bricks.

Frost resistance of building materials - F25-F50, as an experiment was used in the Arctic and Antarctic construction.

Fire resistance indicators - 0.75 h -1.5 h, not flammable.

In terms of resistance to damage to rodents, termites, bacteria, fungi and rot - classification of bioscistance V group.

What is part of Arbolit

Arbolit is blocks consisting of a two-component mixture - filler from wood waste and lightweight concrete with a slight amount of chemical stabilizers for wood resistance. Despite the woody base, country houses are no different, sound and thermal insulation from more expensive materials. The only requirement is obligatory.

The material is fire-resistant, does not shrink, conditionally has 2 varieties - construction (more dense, full) for outer walls and thermal insulation with emptiness for internal works and upper floors. Light blocks are successfully used to facilitate the upper floors in small buildings on soils, where they do not recommend building large and high private houses.

The base of arbolit composition:

sulfate resistant or portland cement;
wood-organic filler;
chemical additives.

Chemical stabilizers are able to give the wood of Arbolit Additional properties:

remove excess pulp polysaccharides for the durability of the material;
significantly increase bactericidal indicators;
adjust the porosity of sawdust, etc.

Under the filler use dry waste of woodworking:

chip
shavings,
sawdust,
crushed bark and needle
solid stalks of farm crops (cotton, cereals, rice straw, etc.), depending on local raw materials.

Thanks to this technology, in order to save, building materials from undergraduate vegetable waste can be made in remote agricultural regions. The release of arbolita with their own hands can be established serially - for local needs.

There are other options, respectively, the production of arbite blocks, for example, is sometimes used liquid glass with ash, lime, sand, slag and other components.

The main properties of blocks

The properties and technology of Arbolit are combined in themselves the dignity of concrete and natural orientation materials for construction. For example, the strength gives it a concrete, and the tendency to self-detention, the deduction of heat and the absorption of odors - from the wood. Like all building materials, the arbolit has its own minuses and obvious advantages.

1. The main advantages of building materials:

multifunctionality in construction is the ability to cast monolithic walls, blocks, plates, jumpers for window and doorways of the required shape and size;
arbolit is amenable to processing (sawing and drilling), makes it possible to obtain blocks of the desired configuration, for example, triangular, under the alignment of a series of the iser roof;
economical building material from undergraduate ingredients;
the simplest production technology and the ability to manufacture blocks directly on a construction site;
the hardened arbolit has a high adhesion, well sufficiently facing and finishing, often without a frame and reinforcing grid;
due to the high heat insulation, the houses from arbolit differ with smaller heating costs than the stone analogs;
arbolit fireproof, despite the wood content;
not susceptible to rotting and damage to fungus;
frost-resistant material;
high sound insulation, it is favorable for use in the construction of houses near the railway canvases and airfields;
the ease of material makes it indispensable on problem soils;
environmentally friendly arbolit is appreciated by allergies and supporters of eco-technologies of construction;
homogeneous material with equal distribution of the mixture;
gives the least all waste during sawing, and broken blocks easily glue with mounting glue;
gives savings time when laying, thanks to large and light blocks;
has a small proportion;
does not give a shrinkage;
perfectly holds fasteners (screws, nails, dowels) and light fittings for decorative trim.

2. Arbolit has its own minuses:

requires the construction of a high concrete foundation for the construction of a country house with waterproofing, if the country area is erected in places of high humidity. This is due to the porosity of the material, and the straightening water is very difficult to remove the outside, because the arbolit is characterized by large water absorption - up to 50-80%. Due to the low moisture resistance, the protective finish of the outer layer is required;
you can not always buy finished blocks, but make arbolit with your own hands is sometimes problematic. In many places, this simple and well forgotten technology is only reborn. Arbolit with their own hands video gives a complete picture of the production technology, which is worth carefully examined before it is done by making it yourself.

Production of Arbolita

The arbium mixture for the molding of blocks is prepared in different ways, depending on the technology. For example, based on a concrete mixer, liquid glass, wood chips, and portland cement brand 500.

For the release of large volumes of Arbolit, special equipment can be rented or acquired. This will require equipment for:

kneading
rambling
masonry in molds,
furnaces for drying
place for curing, protected from moisture.

Detailed industrial production technologies of arbolite blocks have specialized companies that sell them with a set of equipment. In domestic use, you can use the simplest recipes, the method of grinding woodworking waste and arbolite technology, however, and then do not do without concrete mixing and forms to obtain blocks.

Molding blocks from arbolit

The best filler for mass under the arbolit will be a varieneface sawdust in a mixture with a crushed chip, treated with a lime solution, which have already been shutter speed (drying) 3-4 months in air. Sawdust, moistened in a lime solution, stirred and dried, it removes cellulose polysaccharides to eliminate the causes of rotting and swelling.

The form for rectangular blocks can have arbitrary sizes, but it is better to use the standard - 25x25x50 cm. The boards inside should be as smooth as possible. Slices of film linoleum can be additionally treated by KN-3 mastic.

Experienced masters recommend making forms for arbolite blocks from cropping boards with their own hands, and for the convenience of the removal of finished products they advise on the walls to fill the pieces of linoleum. The mixture during the filling of the form can be sealing manually by any suitable to this device. If there is a ready-made vibropress, you can use it.

The filled block is withstanding the day inside the shape, after that it is laid out under the sighting canopy. Some technologies are recommended to withstand blocks under the film for final hydration of 1.5-2 weeks. The low temperature of the warehouse room does not affect the quality of arbolite blocks, but they should not leave them in the frost. In the heat, blocks can dry and sweep up, so they are periodically sprayed with water.

The opilk concrete mass is conveniently kneaded in a metallic trough or drawer, where the sifted sawdresses and the chopped chips are laying, poured with a solution of water with chemical goods. The moistened substrate is well mixed up to uniformity, then the cement is moved, stirred and dry cement is added again until a thick consistency is obtained. The most convenient kneading is obtained in a small concrete mixer.

Related proportion:

1 part of the volume - sawdust plus chopped chips,
1 part of the volume - dry cement,
1.5 parts of water with additives up to 4-5%.

Cement may be more, while the arbolit will be stronger, but heavier, and for porous and hollow material, which goes on insulation and simpleness, cement is added less.

For additives used:

liquid glass;
calcium chloride;
sulphate aluminum or aluminum;
slaked lime.

When filling out the shape with a mixture to obtain arbolit, you can insert 2-3 identical wooden throws to get emptiness. The mass is placed by layers of 3 receptions, followed by a seal with any suitable bits or wooden hammer device. For Arbolita for the first floor, you can add reinforcement between layers. Surplus is necessarily removed, the top is aligned, for example, a wide construction spatula, the form is set under a canopy to frozen concrete.

When removing the finished arbite block, we turn over to a flat area and the hardened material is exposed to a week under the film and finally dries 3-8 days before the masonry.

The first batch is better to make a small one - to verify the properties of the resulting arbolit. You can experience the possibility of sawing, perforation and retention of nails.

Arbolit, which, due to the composition of the composition, is also called the trees, was quite popular in domestic expanses in the middle of the last century. Production technology came to us from Holland, and already in the 60s in the territory of the Union there were about hundreds of plants producing arbolit. It was used for the construction of buildings in the coldest regions of the country, since the material has excellent thermal insulation qualities. In the 90s, many plants went bankrupt, about Arbolite forgot, but the buildings built dozens of years ago were still preserved in excellent condition. Today the material is experiencing a new round of popularity, it is actively advertised, but few people know what arbolit consists of, what advantages and cons is characteristic of it and what kinds it happens. Hurry to correct the situation and make clarity.

№1. The composition of Arbolita

Arbolit is one of the varieties. In the title of the material, French roots are traced: Arbre C French translates as "tree". If you know only this fact, you can guess what main materials are part of Arbolit. So it is:

It is clear that the characteristics of the finished material depend on the quality of raw materials. Since the chips in the Arbolit block is the most, then it is paid to the greatest value. The composition should go to chip - not sawdust, hay, tyrsh or chips (otherwise it will be already ophkaketon). The strength of the material depends on the chip caliber. According to standards, the length of the chip can be up to 40 mm, the width is 5-10 mm, the thickness is 3-5 mm. It is desirable that only chips consisted in the block without any impurities, although a small amount of bark (up to 10%) practically does not affect the strength of the products. Wood grade It is not so important, but usually used, but goes much less often, as you need to use more additives due to wood features.

Cement Use no lower M400 brand, but since it has a feature to quickly lose strength properties during storage, in the production of structural arbite blocks it is better to use the M500 brand cement.

Without chemical additives In the production of arbolit, it is not necessary to do everything in the wines contained in the wood of sugar, which impede normal adhesion. Therefore, in production use in advance well-leaked wood, but it does not save. The surface of the chip is mineralized by lime, calcium chloride, or sulfate alumina.

The ratio of components is regulated by GOST. If, for example, exceed the water content, then the output you can get a block of insufficient strength, and there will be more problems with its manufacture.

Arbolit is produced in several types:

masonry blocks;
hollow blocks;
heat insulating plates;
panels;
the solution for creating monolithic structures and fill in place (like both).

Since the blocks from Arbolita found the greatest application, today they are meant under arbolit. As a rule, they are manufactured with dimensions of 500 * 250 * 200 mm, but products can occur with other parameters.

№2. Production of Arbolita

Production of arbolite blocks is simple, but requires accurate compliance with technology. If short, then the process looks like that. All necessary chemicals add to water. The chip, meanwhile, fall asleep into the mixer, add water to it and are stirred for a short time, then cement is added and mixed for another 3 minutes. The formation is made within 15 minutes in one of the following ways:

manual forming without vibration;
hand molding with vibration;
manufacturing on vibrationan;
manufacturing on a vibrationan with a prune.

Naturally, the mechanization of production allows you to get better blocks with the necessary operational qualities. The mixture pressing ensures the correct distribution of chips in the cement and its complete coating with a cement solution. Vibration is used carefully to achieve the uniform distribution of chips, but do not lead to the precipitation of the cement mortar on the bottom day.

Number 3. Arbolit: pros and cons

The composition of arbium blocks allows us to talk about numerous advantages of material:

excellent thermal insulation. The coefficient of thermal conductivity of arbolite with a density of 400 kg / m 3 - 0.07 W / m * K, a density of 500 kg / m 3 - 0.09 W / m * K, 600 kg / m 3 - 0.11 W / m * K, 800 kg / m 3 - 0.15 W / m * K, and blocks with a density of more than 500 kg / m 3 are considered already structural. According to calculations, for moderate latitudes of the walls of arbolite with a thickness of 38 cm, it is enough to ensure the required heat transfer resistance. In practice, walls are usually built with a thickness of 30 cm, and the inner and outer decoration slightly increase thermal insulation. Together with arbite blocks, it is not bad to apply good, and then the problem of providing heat insulation is quickly solved;
good sound insulation;
excellent vapor permeability, so the optimal microclimate is maintained in the house of Arbolit;
high resistance fire. Material refers to the difficulty (combustion group - Γ1), a refined (B1) and low-forming (D1) materials;
the low weight allows you to save on and simplify the construction process;
simplicity processing;
environmental friendliness;
resistance to and rodents;
high strength. Frames are not formed on the surface of the blocks. Buildings can be erected without additional interconnection reinforcement;
easy installation of fasteners, incl. and self-tapping screws that distinguishes the arbolite block from polystyrene and ceramzite concrete.

Cons of Arbolita:

the need to protect against direct moisture impact. Cement and mineralized chips have low hygroscopicity, but with direct contact with water (for example, rain with the wind) block can worsch and lose a number of its positive properties, so buildings from arbolita are better additionally facing, but there is nothing at home from many other materials. For reasons of aesthetic or protection are also separated. It is worth noting that there are cases of exploitation of buildings from arbolit without an additional exterior finish - in 10 years nothing happened;
not the highest frost resistance. The unit maintains 25-50 frost / defrost cycles depending on the strength, but when the material is protected from direct exposure to moisture, it is possible to significantly extend the service life of the material;
insufficient accuracy of geometry, even subject to all requirements for production. For example, and possess much more accurate geometry. The deviation in block parameters leads to the need to increase the masonry solution, and this leads to the freezing of walls on the seams. Recently, some manufacturers began to resort to milling blocks to improve their geometry;
the price of arbolite blocks is approximately 1.5 times higher than aerated concrete and foam concrete;
abundance in the garage production market of garage production with unknown operational qualities;
to preserve the vapor permeability of the house, you must use only breathing materials for finishing the facade, but this is not a minus - rather, recommendation.

Arbolit today is widely used in private construction for the construction of houses (up to 3 floors), cottages, garages and hozpostroops, is in demand material and in the construction of low-rise production buildings. Shrinkage is 0.4-0.5%.

№4. Arbolita density

The density of arbite blocks is the main indicator that is taken into account during the choice and purchase. The higher the density, the material is more durable and resistant to the loads. On the other hand, a smaller density provides the best thermal insulation qualities, so you should choose blocks depending on the purpose of use.

By density, Arbolite blocks are divided into:

The classification of blocks with the release of a structural-heat insulating material with a density of 450-600 kg / m 3 is also found.

If we are talking about erection of walls at home monolithic technology, The solution of 300 kg / m 3 is a density of 300 kg / m 3 possesses the same good bearing capacity as a block of a density of 550 kg / m 3. In addition, monolithic walls, "grown" with a monolithic method using formwork, do not have cold bridges.

№5. The strength of arbolite blocks

The carrier's ability of arbolite blocks directly depends on the strength to compress the material. With increasing density, strength increases. Strength is determined by the brand and class. Mark - the average value for a whole batch of samples, varies from M5 to M100, where the number shows how much kg can withstand cm 2 surface of the block. In the M75 brand batch, blocks can withstand 65-80 kg / cm 2, and for large blocks is a very significant discrepancy, so today it is often used by grades of strength. The class determines the guaranteed strength, i.e. 95% of all samples must comply with the specified parameter. Arbolit classes fluctuate from B0.35 to B3.5.

The sphere of using arbolite directly depends on its strength:

heat insulating The material has a strength class to B1 and a storage brand to M10;
structural The class of strength to B3.5 and stupid strength to M100.

Blocks B1 can be used when erecting low (up to 3 m) single-storey buildings, for higher buildings it is better to take blocks B1.5, and for 2- and 3-storey houses - blocks B2.0-B2.5.

№6. What to take into account when choosing an arbolit?

Producers of arbite blocks Today, a lot, we will not specifically allocate someone, as in each region there are decent companies and list them for a very long time. On the other hand, everywhere is full and handicraft productionwho are trying to sell frankly bad goods more expensive, and even a certificate of quality is not always a guarantee of actual quality, because we all know how sometimes documents are made. It is best to visit the production, with your own eyes to evaluate the technology and quality of blocks. What are the criteria for checking and how to understand that the product is poor quality?

№7. Arbolite blocks do it yourself

Numerous reviews of private builders indicate that arbolit is better to buy ready, than to produce yourself. The technology seems to be not complicated, but it is difficult to achieve the necessary strength at home, and the labor-intensity of the work is very high. Moreover, the personally made arbolit is better not to use for masonry bearing walls, but or the garage can be built from it, so we give the instruction how to make arbolite blocks with your own hands:

To improve the quality of the material, it is better to get a vibrostol and detachable forms. The composition and proportion of the mixture can vary depending on the desired result.

For use arbolic blocks with a size of 500 * 250 * 300 mm or 500 * 250 * 200 mm, the masonry leads into one or half of the block, the partitions are asserted from blocks 500 * 250 * 150 mm. Preferably after every 3-4 rows of masonry to take a break for drying. When erecting low-rise small buildings, reinforcement is not required - in other cases, the reinforcement is better stacked every 3rd row. The house from Arbolita will have no less than 60 years (it was so many first houses from this material, and they are still in excellent condition) - it is only important to choose high-quality material with the necessary operational qualities.

It is attractive for private construction in that under low weight provides excellent thermal insulation and at the same time it has significant vapor permeability - "breathe". However, these are the cause of a number of material features.

Features

The best and does not have competition material for a bath - of course a tree. Any other options are its substitutes that are missing for some properties. Arbolit is no exception.

The wood concrete consists of 75% of the tree and thanks to this, its quality is to some extent close to the properties. In any case, this material is clearly better than brick or usual. The fact is that if the temperature is supported in the dwelling constant, then the bath is a room where the maximum quick heating is supposed, but only periodically.

Therefore, it acts as the best tree of the tree: provides quick warm-up, good thermal insulation and at the same time removes extra moisture from the bath outside. Walls in a wooden bath never "don't cry."

The last property arbolit does not possess. The chips in it is crushed to such a state so that the difference in the direction of the fibers did not matter. Therefore, we need to consider the trees not as an analogue of the tree, but as a stone building material with high vapor permeability.

Bath from Arbolita (photo)

Sequencing

The foundation for the bath is usually tape, with a mandatory base of 50 cm above the Earth.
The masonry of the walls is the usual, for the bath they offer put in half block, that is, laying "brick" on the edge.
But when finishing the bath, a rather complicated multilayer "pie" is built. The point is to both for the dwelling, and for the bath it is important to comply with the correct order of materials: it should be increased from the inside from the outside.
According to the characteristics for the outer sheat, only the lining of the tree is suitable.

The sequence of construction of the bath from Arbolita with their own hands is obtained:

The inner finish of the tree actually, there is already a violation here, since the vapor permeability of the tree, of course, is higher, the ventilation gap of 1.5-2 cm, vaporizolation and insulation basalt wool, as it refers to non-combustible materials.
Then the wall of arbolitis, windproof film, again ventilating clearance in 2-5 cm and external finish.

A lot depends on the quality of Arbolit, according to numerous reviews of the owners of Bay from Arbolit on the forums.

If the construction arbolite with a large cement content is used, then without vaporizolation and basalt insulation, it is not necessary to do without vapor barrier and basalt insulation: the material by properties are much closer to the opilk concrete, and such a bath will warmly.
If thermal insulation with a large amount of chips is used, then the insulation layer can be omitted.

The surrender of fire safety rules in such a bath is no different from the brick, since the arbolit, unlike the tree, completely non-flamm.

About how to make a garage from Arbolit, do it yourself, read below.

The features of the construction of the bath from Arbolit will tell the owner of such a building in this video:

Garage

For the most part, the garage does not apply to the premises that are heated in winter: the car is a big difference between the temperature in the garage and the air temperature can cause significant damage. However, some insulation is necessary to ensure the minimum comfort of the owner of the box. Arbolit is perfect for this role: reviews about garages from arbium blocks in most cases positive.

The foundation build a light, usually tape. In most cases, do without base.
Wall masonry, with dressing. For masonry, or perlite solution is used. Since the height of the garage does not exceed 2.5 m, then the reinforcement is optional. You can use a plastic reinforcing grid to give the structure a more accurate look.
Since the overlaps in the garage is not assumed, the reinforcing belt in the waters of the walls is not satisfied. Wooden beams or steel farms are used. Roofing - professional flooring.
Arbolit is perfectly holding fasteners, so the frame for the gate is simple. Any racks and shelves are also not a problem.
For reliability, the garage can be separated by plaster, especially when it comes to the rainy region.

Very large importance for the durability of the structure has the quality of the material: the arbolite is unreasonable, including foreign items, gives a shrinkage, creates difficulties when laying and wear out much faster. Judging by the reviews, this question is a stumbling block when choosing a garage material.

Application of arbolit in construction

Use arbolit, even structural for a height of more than 3 floors is undesirable. In this case, a serious increase in the design of steel reinforcement will be required, and the latter, as you know, creates cold bridges. For a 2-3-storey building, a fairly ordinary reinforcing grid.

About how to bind walls from arbolit, what thickness should they be, how to make them with your own hands, read further.

Walls

Arbolite of different species is used in the construction of different walls:

carriers, that is, loaded - for them requires a structural arbolit, the thickness of such a 50 cm wall, although in many lightweight buildings - the garage, cottage, are limited to 30 cm;
self-supporting - Also most often cost a thickness of 30 cm from blocks of 30 * 20 * 50 cm;
partitions - The inner walls are built with a thickness of 20 cm from blocks 20 * 20 * 50 cm.

Blocks on cement-sand or perlite solution. The latter is closer in thermal insulation indicators, and therefore is the best choice. For masonry, a slightly infused material is chosen or is abundantly watering it with water before applying a masonry solution: otherwise moisture from the solution will be in blocks earlier than the masonry will have time to grab.

According to GOST, we are produced from the ready-made outer finishing layer. The inner layer may appease - plaster, maybe there is no. In fact, blocks rarely meet with any finished finish.

Arbolit needs to be protected from moisture action, as the material is too well absorbs. Most often, the protective layer for walls from Arbolit is the plaster, as we are talking about a structural material, in which vapor permeability is lower than that of thermal insulation. So the contradictions do not arise.

The interior decoration of walls from Arbolita has no restrictions - from the tile to wallpaper. Since the surface has high adhesion, any cladding is perfectly held on the walls from Arbolit.

The next video is devoted to the construction of walls from Arbolit:

Floors

The floor from the arbolit of unambiguous approval, judging by the reviews, does not cause. It is used for this that you have to either do yourself or order separately from blocks. The thickness of the screed layer, as well as the layer of insulation reaches 10-15 cm, which is not always profitable.

Possible laying of arbolite on the base of the floor or for insulation on a concrete tie.

In the first case, the cement-sand base is preparing and very carefully: the use of vibration installations is required. Then the fittings are stacked - cells 25 * 25 cm, and is filled with ordinary concrete. Waterproofing is carried out - or primer, and then poured a screed from arbolit.
Two-layer is stacked on the concrete base: 7 cm made of arbolitis with a large chip content - heat-insulating, and the last 3 cm - from a more dense trees.

Such a floor is possible only at high ceilings. Read about overlapping from Arbolita further.

Overlapping

For overlaps, special combined plates have been developed, as the strengths of arbolite as such is clearly not enough for the product.

The stove of three layers is: the bottom of the M25 or M35 concrete with the reinforcement grid, with a diameter of 10-12 mm. The armature is pre-tense, which significantly increases the reliability of the product. The middle layer consists of thermal insulation arbolit, and the upper - from the concrete of the same brand.
There may be another variant in which the bottom layer and the ends of the plate, perpendicular planes of the lower layer, consists of a concrete. Such a stove is cheaper and prevents an uneven compression of arbolit in the second layer.

A plate is produced up to 4.8 m long. However, for private construction, judging by the reviews of the plate is preferable to 3.5 m.

On whether it is possible to make a foundation for the house from Arbolit, do it yourself, read below.

More details about overlapping from opilk concrete will tell this video:

Foundation

Arbolit - material prone to water absorption due to its porous structure, and therefore the construction of the foundation is impossible. The trees are defenseless before dampness and groundwater.

Woodcloth is not enough well-studied material to recommend its widespread use. However, there are areas where arbolit has already deserved its good reputation and can be used without feet.
