Aerated concrete is a modern construction material that is often used in the construction of low-rise buildings. The people who created it claim that it has excellent thermal insulation properties, is not very heavy and has a high level of durability. In addition, it is easy to install, it does not burn and has a beneficial effect on the environment.
According to a number of different sources, when the temperature drops below zero, it becomes wet and eventually breaks down. In addition, the problem may lie not in the component itself, but in how it is used in the process of construction or repair. However, in order for a house built from aerated concrete blocks to have a long service life and at the same time be reliable, manufacturers need to establish specific rules.
The pioneer in the autoclaved aerated concrete market was the YTONG company, which was the first to introduce this material in the construction industry anywhere in the world. The production process of autoclaved aerated concrete was first developed in Germany. Since it is made from purely natural components, it does not contain any chemicals that may be harmful to humans or the environment. In the second half of the 1970s, the first plant for the production of aerated concrete blocks was launched in Russia. Initially, each block had a simple appearance. In the future, the number of available products increased, which significantly reduced the complexity of building buildings from aerated concrete. And now the company is the leader in the construction of this durable and reliable material in Novosibirsk https://www.dreamhouse-nsk.ru/ with which you can build the house of your dreams at very reasonable prices.
Currently, enterprises in Russia produce:
– blocks that can be used for partitions and building walls;
– blocks in the form of a U-shaped trough;
– forms consisting of blocks;
- blocks of floors, which are considered prefabricated or manufactured in one piece;
- reinforced jumpers
– O-blocks, which are universal building blocks that can be installed in chimneys and ventilation openings;
- ladder components
Blocks made of autoclaved aerated concrete, produced by some manufacturers, have a length of 600 millimeters, a width of 300 millimeters and a height of 200 millimeters.
In the production of building blocks, which are created in huge factories using the most modern technologies, autoclaved aerated concrete is used. The casting process is used in the production of liquid mixtures (water content in the mixture is about 60 percent of the weight of the finished product).
Dry components, such as sand mortar and binder, are combined with water heated to 400 degrees Celsius and mixed in an aerated concrete mixer. Then the mixture is subjected to further mixing after adding an aqueous suspension of aluminum powder to it. After the mass increases in size, it is packed in metal forms, which are then filled with the mixture to the edges. In order to get rid of excess mass, metal strings are used. Additional items are loaded into the autoclave, which operates at a temperature of 1750 degrees Celsius and a pressure of 0,8 megapascals.
It is the autoclave treatment that gives aerated concrete blocks an impressive level of strength. However, there are aerated concrete blocks on sale that have not been baked in an autoclave. Such blocks can be used in construction. Of course, they are made of porous concrete in which there are cells. On the other hand, they do not have the best shape and strength, since they are made by hand and do not adhere to the technical procedure established by the standards. Therefore, there is so much hope for the durability of the material. Autoclaved aerated concrete was often used during the construction of houses in the Soviet era. These houses are still standing, and there is no visible evidence that they have been damaged.
