 The concrete aerated block is made of siliceous materials (sand, fly ash, and silica-containing tailings, etc.) and calcareous materials (lime, cement) as the main raw materials, mixed with aerating agent (aluminum powder), through batching, mixing, Lightweight porous silicate products made by pouring, pre-curing, cutting, autoclave, curing and other processes. It is called concrete aerated block because it contains a large number of uniform and small pores after it is gasified.
