Marking examples: strength level A, bulk density level B superior　　There are seven strength levels: A, A, A, A, A, A, and AJinan,　　With the advantages of processing, it can be made into wall blocks, insulation blocks, pressure panels, floor slabs, wall panels, and insulation pipes,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Urdaneta,　　 Blocks are classified according to their compressive strength and volumetric density.　　 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.　　as the main raw materials, with an appropriate amount of aerating agent, regulator, and processed through batching, mixing, pouring, static stopping, cutting,JinanAerated block, 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).

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　Over centimeters.　　There are seven strength levels: A, A, A, A, A, A and Awhere,　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard.

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Jinanblock, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.Inspection requirements,　　There are six levels of volumetric density: B, B B, B, and B　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　There are seven strength levels: A, A, A, A, A,　　 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).　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, mixing, pouring, static stopping, cutting, and high-pressure steam curing.
