Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　There are seven strength levels: A, A, A, A, A, and ALiaocheng,　　 When laying aerated bricks, the distance between the bottom of the wall needs to be filled with small solid bricks, but the maximum cannot exceed　　There are six levels of volumetric density: B, B,Liaochengautoclaved aerated concrete block, B, B, and BLevadeia,　　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, 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).　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).
