AAC is a product of concrete technology is advanced, which in the early twentieth century in Sweden was invented.

in the year 1920 ad, Dr. Axel Ericsson, master, sweetheart, technology, building, in the Institute of royal Technology, Stockholm, Sweden. for the first time, gas concrete (Gas Concrete) to build. He observed that the mixture of lime and silica along with the cement powder and the aluminum powder material, concrete creates a porous and very light.

but this is the product of the resistance, many did not. "After testing multiple get that if the action collection of this material in high temperature and pressure, high done, a product concrete is porous with a high resistance to it, is due to the presence of gas bubbles in it, a good insulation is also considered. This product after changes in the formulation of Autoclaved Aerated Concrete and refer to the AAC was called.

about 50 years ago, the Germans also use this technology, and AAC under different commercial names for the production. Sync with Sweden and Germany, the UK and Eastern European countries is also ash to replace the Silica has long been that the AAC block produced in the construction they use.

now, with small changes in formulation and process related to AAC, etc. significant changes in the structure, it provide come and these changes enhance the physical properties of mechanical and AAC. In recent years, more than 450 producers in 41 countries around the world, AAC to produce and market supply.

(Autoclaved Aerated Concrete (AAC, who at the same time, means concrete sponge is known from the construction materials in the developed light-weight is that the body, etc. insulation and resistance against fire to form simple supply.

products, AAC, includes blocks, panel, wall, etc. panel, ceiling, and floor, and , that can mix (cement) for the isolation, superfoods, etc. for domestic consumption and foreign made. In addition to isolation, other rating this product on the building, consumption, quick and convenient it is.
