Autoclaved aerated concrete blocks Manufacturer's introduction Autoclave Aerated concrete block It is a solid block composed of cement, slag, sand, lime, etc. as the main raw materials to participate in the air entraining agent, which is stirred to shape and autoclaved for curing. Its characteristics are: light weight, only 500~600kg/m3 for Grade 05.06; High compressive strength, up to 3.5~7.5Mpa, good thermal insulation performance, thermal conductivity of 0.11~0.16w/(m.k), sound absorption and insulation performance; High fire resistance; It is easy to process, and can be nailed, cut and sawed on it for easy construction. However, due to the loose material, strong water absorption and poor water dispersion of the wall, cracks, mildew and other defects are likely to occur in the construction if the control is not good.
Autoclaved aerated concrete blocks can adopt different processes to stop consumption according to the type of original materials, quality, technological characteristics of equipment, etc. Under normal conditions, fly ash or silica sand is ground into slurry by adding water, and then mixed with powdered lime, appropriate cement, gypsum and foaming agent. After average mixing, it is injected into the mold frame. After static foaming and solidification, it is cut into blocks or plates of various specifications, which are sent into autoclaves by steam curing trucks. Porous lightweight aerated concrete products are formed under high temperature saturated steam curing.
Autoclaved aerated concrete block is a kind of lightweight and empty building materials. It is made of cement, lime, slag, fly ash, sand, gas generation materials and other raw materials through grinding, batching, pouring, cutting, steam curing, milling and other processes. The autoclaved aerated concrete block is named because it contains a large number of average and small air holes in the product after being aerated. It has the advantages of light weight, good thermal insulation performance and processability. It is one of the materials of light wall that have been applied early and widely in China, and has a good prospect. Steam curing aerated concrete equipment came into being to meet the market demand.
