There are six levels of volumetric density: B, B, B, B, B, and B　　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.Dongping,　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　 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.Nalut,　　There are six levels of volumetric density: B, B, B, B, and B　　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).　　There are six levels of volumetric density: B, B B, B, and B

　　 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).　　Blocks can be produced using different processes based on material types, quality, fly ash or　　If the purchasing unit needs other specifications,Dongpingautoclaved aerated concrete block, they can negotiate with the production factory to determine.Total quality management,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　as the main raw materials, with an appropriate amount of aerating agent, regulator, and processed through batching, mixing, pouring, static stopping, cutting, and high-pressure steam curing.
