　　Marking examples: strength level A, superior　　Marking examples: strength level A, bulk density level B, superiorJining Jiaxiang,　　Aerated blocks, also known as aerated bricks, aerated blocks, aerated concrete blocks, autoclaved aerated concrete blocks,Jining JiaxiangAerated block, and aerated concrete blocks　　 Blocks are classified according to their compressive strength and volumetric density.Choma,　　There are six levels of volumetric density: B, B, B, B, and B　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, test methods, inspection rules, product quality instructions stacking, and transportation of autoclaved aerated concrete blocks.　　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. The unit volume weight of autoclaved aerated concrete blocks is one-third of 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).

　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size product grade,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification and standard number.Process inspection, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　Silica sand and slag are ground into slurry with water, then powdered lime, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　 Blocks are classified according to their compressive strength and volumetric density.Jining Jiaxiang,Jining Jiaxiangaerated block brick,　　 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,Jining Jiaxiangblock, and all parties using this standard should explore the possibility of using the latest versions of the following standards.　　There are seven strength levels: A, A, A, A, A, A, and A
