　　There are six levels of volumetric density: B, B,Dezhou Qingyunblock, B, B, B, and B　　Marking examples: strength level A, bulk density level B, superiorDezhou 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,　　There are six levels of volumetric density: B, B, B, B, B, and BHua Hin,　　There are seven strength levels: A A, A, A, A, A, and A　　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, technical requirements, test methods, inspection rules, product quality instructions,Dezhou Qingyunautoclaved aerated concrete block, stacking and transportation of autoclaved aerated concrete blocks.

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions stacking, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　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.Quality improvement,　　as the main raw materials, with an appropriate amount of aerating agent, 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, 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).　　 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.　　There are seven strength levels: A, A, A, A, A, A, and A

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.Marketing Department,　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　Blocks can be produced using different processes based on material types, quality, and equipment process characteristics. Generally, fly ash or　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, and compressive strength: excellent product (A) first-class product (B),Dezhou Qingyunaerated block brick, qualified product (C).Dezhou Qingyun,　　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, 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, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).
