　　Marking examples: strength level A, bulk density level B, superior　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Qingyun,　　 days, so that the strength can reach the standard. At the same time, it is required that the brick body should not have cracks and the surface should be clean,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Bogla, B, B, B,Qingyunaerated block brick, B, and B　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density and compressive strength: excellent product (A), first-class product (B), A, A, A, A, A, and A　　The construction specifications for aerated block wall masonry require that: Air bricks used for wall masonry must have a production date exceeding　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Price　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A) first-class product (B), qualified product (C).　　 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.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Installation requirements,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing,Qingyunautoclaved aerated concrete block, pouring,Qingyun block, 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).　　Silica sand and slag are ground into slurry with water, gypsum, and foaming agent are added, stirred,　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard.
