　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules product quality instructions, and transportation of autoclaved aerated concrete blocks.　　Promoting the application of earth blocks for external wall self insulation stacking, autoclaved sand aerated concrete blocks, and internal partition wall autoclaved sand aerated concrete blocks　　Marking examples: strength level A, bulk density level B, superiorCustomer first,　　 Blocks are classified according to their compressive strength and volumetric density.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　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. 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).
