How to build a house of aerated concrete blocks: video. Blocks of aerated concrete are a reliable building material that is environmentally friendly and durable. Aerated concrete is very similar to pumice.
The material for making concrete is cement, sand, water, and an additive for a blowing agent. The density of the material determines the purpose of the finished product. Therefore, there are three types of aerated concrete.Cellular concretedensity of 1000-1200 kg / meter cubic. used for the construction of multi-storey buildings. For houses and cottages in three floors applythermal insulation structural concretewhose density is 500-1000 kg / cubic meter. For insulation of walls, floors, attics and roofs fitconcrete with a density of 200-500 kg / cubic meter.
Aerated concrete has a thermal conductivity of 3 times the brick. It differs in economy, frost resistance, has good sound insulation, fire resistance, it is easily processed. Increased hygroscopicity is a significant disadvantage of reinforced concrete.For this reason, walls of this building material should be protected from precipitation, for example, by vapor-permeable plaster. Also, such a structure is faced with brick, planks or siding, not forgetting the need for a ventilation gap between the wall and the cladding. The walls of rooms with high humidity are covered with ceramic tiles, protecting them from dampness.
When building a building using aerated concrete blocks, special lifting equipment is not needed, because the block weighs 30 kg. The laying of blocks is overlapped. For bonding using a special adhesive solution. Cement mortar is suitable for laying the first row of the foundation to avoid surface irregularities. The second row and the rest are put only on the glue, which is applied with a thin layer of a spatula.
First, we suggest to get acquainted with the material of aerated concrete and the rules of his choice.
