This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　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).Lincheng　　Aerated blocks are divided into fly ash aerated concrete blocks and sand aerated concrete blocks, among which fly ash autoclaved aerated concrete blocks　　 Blocks are classified according to their compressive strength and volumetric density.Diego de Almagro,　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard. 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.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level,LinchengAerated block, specification size, product grade, and standard number.　　There are six levels of volumetric density: B, B, B, B, B, and B

　　There are six levels of volumetric density: B, B, B, B, B, and B　　 According to the prescribed standards, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　There are seven strength levels: A, A, A, A, A, A, and AInspection standard,　　 Blocks are divided into three levels based on dimensional deviation, 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,Linchengblock, 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.
