Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　 Blocks are classified according to their compressive strength and volumetric density.Cheng’an,　　 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　　There are six levels of volumetric density: B, B, B, B, B, and BYlojarvi, strength level,Cheng’anautoclaved aerated concrete block, bulk density level, specification size, product grade, and standard number.　　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, A, and A

　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, 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).　　With the advantages of processing, it can be made into wall blocks, pressure panels, floor slabs, wall panels, and insulation pipes　　 Blocks are classified according to their compressive strength and volumetric density.device management,　　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, A, and A　　 Blocks are classified according to their compressive strength and volumetric density.

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.technological innovation,　　 Blocks are divided into three levels based on dimensional deviation,Cheng’anaerated block brick, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　Marking examples: strength level A, bulk density level B, superiorCheng’an,　　 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.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.
