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).Mutengene,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　There are six levels of volumetric density: B, B, B, B B, technical requirements and B　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.

　　Marking examples: strength level A, bulk density level B superior　　 When constructing aerated bricks, it is required that the mortar strength must meet the design requirements.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Yuncheng, Hezeautoclaved aerated concrete block, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.quality　　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.
