bulk density level B, superiorWeishan,　　 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　　Marking examples: strength level A, bulk density level B, superiorContramaestre,　　There are six levels of volumetric density: B, B, B, B, B, and B　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Marking examples: strength level A, bulk density level B, superior

　　 Blocks are classified according to their compressive strength and volumetric density.　　Aerated blocks, also known as aerated bricks, aerated blocks, aerated concrete blocks,Weishanaerated block brick, and aerated concrete blocks　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, 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).Application process,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　 Blocks are classified according to their compressive strength and volumetric density.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, 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, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.Customer first　　There are seven strength levels: A, A A, A, A, A, and A　　Condensing materials. As the main raw material. This aerated concrete block has the advantages of insulation, moisture resistance,Weishanautoclaved aerated concrete block, and lightweight.　　 Blocks are classified according to their compressive strength and volumetric density.Weishan　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 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).　　 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.
