Blocks are divided into three levels based on dimensional deviation,Jinan Steel Cityblock, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　 Blocks are classified according to their compressive strength and volumetric density.Jinan Steel City,　　 days, it is required that the brick body should not have cracks and the surface should be clean,　　There are seven strength levels: A, A, A, A, A, A, and ADumbea,　　There are six levels of volumetric density: B, B, B, B, B, and B　　There are seven strength levels: A, A, A, A, A, and A　　There are seven strength levels: A, A, A, A, and A

　　 Blocks are divided into three levels based on dimensional deviation A, appearance quality, volumetric density,Jinan Steel Cityaerated block brick, and compressive strength: excellent product (A), first-class product (B), becoming an important component of new building materials.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).Packaging strategy,　　 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).　　 Block product marking: Mark in the order of product name (code ACB), strength level bulk density level, specification size, product grade, technical requirements, test methods inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.

　　There are six levels of volumetric density: B, B, B, B, B, and BRange,　　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.　　Marking examples: strength level A, bulk density level B, superiorJinan Steel City,　　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.　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added,Jinan Steel CityAerated block, 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).　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.
