At the time of publication of this standard, all versions shown are valid. All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.Wu’an,　　The construction specifications for aerated block wall masonry require that: Air bricks used for wall masonry must have a production date exceeding　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Kongens Lyngby,　　There are seven strength levels: A A, A, A,Wu’anblock, A, A, and A　　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.　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, 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).

　　 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).　　Aerated blocks are divided into fly ash aerated concrete blocks and sand aerated concrete blocks, A, A, A, A and ADiscount, bulk density level B, superior　　Marking examples: strength level A, bulk density level B, superior　　There are six levels of volumetric density: B, B, B,Wu’anaerated block brick, B B, and B
