Foam concrete is a practical building material. Concrete with a porous structure is used for the construction of industrial facilities, utility buildings, private houses. Foam concrete is made from a cement-sand mortar with the addition of foaming ingredients in compliance with the required proportions.
In construction, foam concrete of varying degrees of density is used. The scope of application depends on the brand of foam concrete. The production of foam blocks is regulated by the requirements of GOST. The greatest demand is foam block d400 , having a low density - 400 kg /m³, are used to insulate interfloor reinforced concrete floors, interior partitions, load-bearing walls, under-roof space, soundproofing of premises. The strength of D400 foam concrete is 9 kg /cm² (class B0.75). At the same time, the integrity of the material is preserved, and cracks do not form. The thermal conductivity coefficient is 0.09-0.10. The high thermal insulation performance of the D400 reduces heating costs.
Properties of aerated concrete
The material is functional; distinctive features:
- strength - foam concrete retains its performance and structure for a long time;
- heat resistance - the material does not collapse during temperature extremes, does not change its structure during accelerated thawing after deep freezing;
- correct block geometry;
- ease of installation;
- light weight;
- high noise insulation;
- fire resistance - resistant to high temperature, open flame;
- the material is environmentally friendly - it does not emit harmful substances during operation;
- easily handled with hand tools.
This building material has an excellent value for money.
