At the time of publication of this standard,Changqing block, all versions shown are valid. All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.　　as the main raw materials, with an appropriate amount of aerating agent, 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).　　There are seven strength levels: A, A,Changqingaerated block brick, A, A, A, A, and A

　　 Blocks are divided into three levels based on dimensional deviation, volumetric density, and compressive strength: excellent product (A), qualified product (C).　　Condensing materials. As the main raw material. This aerated concrete block has the advantages of insulation, moisture resistance, and lightweight.　　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.
