　　 Blocks are classified according to their compressive strength and volumetric density.　　Advantages of aerated bricks: Concrete is used as the main raw material for aerated bricks, which not only　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Total quality management,　　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).　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　There are seven strength levels: A, A, A, A, A and Amanufacturer,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　 When laying aerated bricks, it is necessary to make batches of poles according to the height of the bricks, and then erect them at the corners of the wall　　 Blocks are classified according to their compressive strength and volumetric density.Handan Cheng’an,Handan Cheng’anblock,　　 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).　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods inspection rules,Handan Cheng’anAerated block, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　There are seven strength levels: A, A, A, A, and A
