[0002] Aerated bricks are widely used in the construction industry as a lightweight, heat-insulating and heat-insulating building material. Aerated bricks are porous silicate products made of siliceous and calcareous materials as the main raw materials, mixed with gas-generating agents, stirred with water, and formed by chemical reactions to form pores. The products are made through processes such as casting, pre-curing cutting, and autoclaving. The autoclave is the key equipment in the autoclaving and curing process of aerated bricks, which is used to treat the aerated brick body with high-temperature and high-pressure steam to improve its strength and performance.
