　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density,plainaerated block brick, 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, and equipment process characteristics. Generally, fly ash or　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.wholesaler,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, 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 cutting, and the insulation performance is - times that of clay bricks, The sound insulation performance is 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, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.
