All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.　　 Blocks are classified according to their compressive strength and volumetric density.Xingtai Qinghe,　　Blocks can be produced using different processes based on material types, quality, and equipment process characteristics. Generally, fly ash or　　There are six levels of volumetric density: B, B, B, B, B, and BDerna,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　There are six levels of volumetric density: B, B, B, B, and B　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements test methods,Xingtai QingheAerated block, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.

　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, cutting and high-pressure steam curing. The unit volume weight of autoclaved aerated concrete blocks is one-third of that of clay bricks, The sound insulation performance is twice that of clay bricks, the impermeability performance is more than twice that of clay bricks and the fire resistance performance is - times that of reinforced concrete. The masonry strength of the block is about % of its own strength (% for red bricks).　　Silica sand and slag are ground into slurry with water, then powdered lime, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, cutting, and high-pressure steam curing.
