as the main raw materials, with an appropriate amount of aerating agent, regulator bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, 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).　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Ningjinautoclaved aerated concrete block, test methods, inspection rules, product quality instructions, stacking and transportation of autoclaved aerated concrete blocks.Ningjin,　　Over centimeters.　　There are six levels of volumetric density: B, B, B, B, B, and BCurtea de Arges,　　There are seven strength levels: A, A, A, A, A, and A　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), all versions shown are valid.
