Among the large number of building materials that have recently appeared on the market, aerated concrete should be especially noted, which is usually used in the form of ready-made blocks. This material is a kind of cellular concrete. Its performance characteristics directly depend on the material and the method of its manufacture..
Typically, stone light aerated concrete blocks consist of a binder, which includes sand and lime. To obtain the cellularity of the blocks, that is, to ensure the presence of a large number of pores in the material, aluminum powder is added to the mixture. All components of the mixture are thoroughly mixed, after which a block of certain sizes is formed from it, which is then placed in a special chamber with a high level of humidity.
After that, elements of the required size are cut from the block, which are further processed in an autoclave with water vapor under high pressure at high temperatures. Ultimately, a block with a precise geometric configuration is obtained, which has high strength and other unique properties of this material..
Experts note the good moisture resistance of the material as the main advantages of aerated concrete blocks. This became possible due to the unique porous structure of the material. Studies have shown that even if the level of humidity in the ambient air is about 90%, this indicator in aerated concrete blocks will not exceed 8%. Thanks to this, aerated concrete can be used to build houses in a humid climate..
In addition, aerated concrete is lightweight, which greatly facilitates the construction process using this material. Aerated concrete is characterized by high frost resistance and fire resistance, excellent resistance to various biological influences. The low thermal conductivity of the material, its environmental friendliness, durability and high sound-insulating properties are also important. Aerated concrete blocks have strict dimensions, which makes it possible to erect buildings from them with high accuracy.
At the same time, when planning to build a house from aerated concrete blocks, it should be borne in mind that such a material, if the load is incorrectly calculated, cracks rather quickly due to its porous structure, and also has a rather high cost.
