Today, aerated concrete is one of the most high -tech, modern and high -quality building materials, therefore, aerated concrete is produced in Krasnodar and many other regions of Russia. The scope of its application depends on the degree of strength, since it is different. The most fragile forms of aerated concrete blocks are an excellent insulation. Incidentally, it was originally used only to warm buildings, and later it began to be used as a durable building material instead of brick. More durable forms are used as thermal insulation material, and strong category is used in the construction of low -rise buildings. The most durable brands can be used for the construction of powerful structures, such as supporting walls, etc. D. At the same time, the house from the gas block is environmentally friendly, has thermal insulation, fire -resistant and durable.
In the production of aerated concrete blocks, water, fillers (gypsum, sand, etc. are used.), Portland cement and most importantly — a generator (aluminum powder). Water must meet the norms GOST 23732-79. In other words, any drinking water will come in handy for the preparation of the mixture. When using technical water, water from surface sources is suitable, which has soft and medium rigidity, as well as non. Its temperature should be approximately 45-50 ° C.
Portland cement GOST 10178-85 M500D0 and M400D0 brand is suitable for the manufacture of non-vomiting aerated concrete. Each cement plant has its own specifics of the composition of cement, so you can choose a specific recipe for non -avoiding aerated concrete using a specific type of cement. The exception is only hydrophobic, highly sulfate, puzzolan and sulfate cements.
Fillers for the production of aerated concrete blocks can be used by different: dispersed, inert or active. But they must meet some criteria: the maximum module of the size of 1.5; The chemical composition should not interfere with the process of gas formation and the content of clay and silty substances should be minimal. Fillers can be both natural and technogenic. Often, sand is used, to which different additives are dominated (chalk, gypsum)
And the most important component that gives to aerated concrete uniqueness is the generator. It has a gas -forming effect and is a powdered dry mixture based on aluminum powder.
Based on the components of aerated concrete blocks, it can be argued that they are absolutely environmentally friendly, have thermal insulation and strength, and given that the price of aerated concrete is quite low, then we can talk with nonsense about the popularity of this type of building material.
