| Title of the article | A study of the basic characteristics autoclaved gas concrete |
| Abstract. | Autoclaving treatment of aerated concrete is carried out not only to speed up the process of hardening of the mixture but the main point is that, in an autoclave at a temperature of +180 °C and pressures up to 14 bar a new mineral – tobermorite is formed in aerated concrete. This increases the strength of the material and, most importantly, the shrinkage is reduced several times. Due to its characteristics, autoclave concrete has a lot more methods of use. Aerated autoclaved concrete has low fracture toughness and resistance to frost. Autoclave treatment allows less time to obtain products with a sufficiently high strength at a reduced flow rate of the binder. Aerated concrete of autoclaved manufacturing method is made from a mixture of natural raw materials: sand, cement, quicklime, water and a small amount of aluminum powder. Because of the chemical reaction of lime and aluminum powder the mixture foams, and pores of various sizes, filled with air, formed within. Due to its characteristics, autoclave concrete has a lot more methods of use. Aerated autoclaved concrete has low fracture toughness and increased resistance to frost. Autoclave treatment allows to obtain products with a sufficiently high strength in less time. |
