This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).Mount Taishan,　　Silica sand and slag are ground into slurry with water, then powdered lime gypsum, stirred, and injected into the mold frame　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B) qualified product (C).Mboursou Lere,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Mount Taishanaerated block brick, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　There are six levels of volumetric density: B, B, B, and B

　　Marking examples: strength level A, bulk density level B, superior　　 According to the prescribed standards, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　 Blocks are classified according to their compressive strength and volumetric density.Customer first,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Marking examples: strength level A, bulk density level B, superior　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added,Mount TaishanAerated block, 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, and the insulation performance is - times 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).
