In the production of concrete work at air temperature above 25 ° C and relative humidity, less than 50% should apply rapid portland cements, the brand of which should exceed the brand strength of the concrete at least 1.5 times. Class B22.5 concrete and higher cements are allowed, the brand of which exceeds the brand strength of the concrete in less than 1.5 times, subject to the use of plasticized portland cements or the introduction of plasticizing additives.

Cements should not have a false grasp, have a temperature above 50 ° C, the normal thickness of the cement test should not exceed 27%.

2.64. The temperature of the concrete mixture in concreting structures with the surface module more than 3 should not exceed 30-35 ° C, and for massive structures with a surface module less than 3-20 ° C.

2.65. When it appears on the surface of the underlined concrete, the cracks due to the plastic shrinkage is allowed its re-surface vibration no later than 0.5-1 hours after its styling.

2.66. Care for freshly lined concrete should be started immediately after the end of laying a concrete mix and exercise to achieve, as a rule, 70% of the design strength, and with the appropriate justification - 50%.

The freshly stated concrete mix in the initial period of care should be protected from dehydration.

Upon reaching the concrete of the strength of 0.5 MPa, the subsequent care for it should be to ensure the wet state of the surface by the device of the moisture-intensive coating and its humidification, withstanding the open surfaces of the concrete under the layer of water, continuous moisture spraying over the surface of the structures. At the same time, periodic watering with water of open surfaces of hard concrete and reinforced concrete structures is not allowed.

2.67. To intensify the hardening of concrete, it is necessary to use solar radiation by covering structures with a roll or leaf translucent moisture-proof material, coating them with film-forming compositions or lay a concrete mixture with a temperature of 50-60 ° C.

2.68. In order to avoid the possible occurrence of the thermallyspotable state in monolithic structures, with direct exposure to sunlight, the freshly lined concrete should be protected by self-disseminating polymeric foams, inventory heat insulating coatings, a polymer film with a reflection coefficient of more than 50% or any other thermal insulation material.

Special methods of concreting

2.69. Based on specific engineering and geological and production conditions in accordance with the project, the application is allowed to apply the following special methods of concreting:

vertically moved pipe (HPP);

ascending solution (BP);

injecting;

vibration phase;

laying a concrete mix of bunkers;

submissions of the concrete mix;

pressure concreting;

radine concrete mixes;

cementing by a boosmest way.

The BP method with pouring an outline of a rubble cement-sandy solution is allowed to be used at depths up to 20 m for the construction of constructs from the class concrete to B25.

With a depth of concreting from 20 to 50 m, as well as during repair work to enhance structures and restoration construction, the pouring of a chicken filler with cement mortar without sand should be used.

2.72. Injecting and vibrating pressure methods should be used for concreting underground structures preferably thin-walled from concrete class B25 on the filler of the maximum fraction of 10-20 mm.

2.76. Concretion by Radin with a low-cemental rigid concrete mixture should be used to build flat extended structures from a concrete class to B20. The thickness of the dotted layer should be taken within 20-50 cm.

2.78. When underwater (including under clay solution), concreting must be provided:

isolation of concrete mix from water in the process of transporting it under water and laying into a concrete structure;

formwork density (or other fence);

control over the state of formwork (fencing) in the process of laying a concrete mixture (if necessary for the forces of divers or with the help of underwater television installations).

2.79. The timing of the palampization and loading of underwater concrete and reinforced concrete structures should be established according to the results of the test of control samples that have been furified under conditions similar to the conditions of hardening concrete in the design.

achievements of concrete in the shell of strength of 2.0-2.5 MPa;

removal from the surface of the underwater concrete of sludge and weak concrete;

ensuring reliable communication of the newly stacked concrete with hardened concrete (stages, anchors, etc.).

In concreting under clay solution, the breaks of longer than the catch of the concrete mixture are not allowed; If the specified restriction is exceeded, the design should be considered defective and not subject to repair using the VPT method.

2.81. When the concrete mixture is applied to the water with bunkers, free dropping of a mixture through a layer of water is not allowed, as well as the recreation of the contained concrete with a horizontal movement of the bunker.

2.82. When concreting, it is necessary to produce the newly incoming portions of the concrete mix, not closer to the rejuvenation of the concrete mix, not closer than 200-300 mm from the water rugging, not allowing the sprout of the mixture over the slope into the water.

The surface surface of the laid concrete mixture for the time of setting and hardening should be protected from erosion and mechanical damage.

2.83. In the device of the "Wall in the Soil" type, tranche concreting should be performed by sections of no more than 6 m using inventory intersection separators.

In the presence of a clay sliding solution, the concreting section is produced no later than 6 hours after filling the solution into the trench; Otherwise, the clay solution should be replaced with the simultaneous formulation of the sludge, which settled on the bottom of the trench.

Deviations on the installation of mounting elements, the position of which may change in the process of their continuous consolidation and loading by subsequent structures, should be assigned to the PPR with such a calculation so that they do not exceed the limit values \u200b\u200bafter the completion of all installation work. In the absence of special instructions in the PPR, the value of the deviation of the elements during the installation should not exceed 0.4 limiting deviation to the acceptance.
3.21. The use of installed structures to attach cargo polystopes, tap blocks and other lifting devices is allowed only in cases provided for by the PPR and coordinated when necessary with the organization that completed working drawings of structures.
3.22. Installation of structures of buildings (structures) should be started, as a rule, with a spatial-resistant part: a blessing cell, stiffener cores, etc.
Installation of structures of buildings and structures of a large length or height should be produced by spatial-resistant sections (spans, tiers, floors, temperature blocks, etc.).
3.23. Production quality control of construction and installation work should be carried out in accordance with the SP 48.13330.
