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).　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　 Blocks are divided into three levels based on dimensional deviation, appearance quality,Jinan Steel Cityblock, volumetric density, and compressive strength: excellent product (A), first-class product (B), A, A, A, A, A, and AMeticulous workmanship,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, product grade, and standard number.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, 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.

　　 Blocks are classified according to their compressive strength and volumetric density.Free consultation,　　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.
