　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Blocks can be produced using different processes based on material types, quality, and equipment process characteristics. Generally, fly ash or　　There are six levels of volumetric density: B, B, B, B, B, and BQuality risk,　　There are seven strength levels: A, A, A, A, A, A, and A　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added and processed through batching, mixing, 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, 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).　　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.
