This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping,Shexian Countyaerated block brick, 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,Shexian Countyblock, 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).Shexian County,　　Blocks can be produced using different processes based on material types, quality, and equipment process characteristics. Generally, fly ash or　　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.Ankazoabo,　　There are seven strength levels: A A, A, A, A A, and A　　 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.

　　 Blocks are classified according to their compressive strength and volumetric density.　　Block. And it is required that each design unit should indicate the strength of the materials in the design documents when selecting them,【 Conclusion 】 Although there are differences in the production process and performance between autoclaved aerated concrete blocks and autoclaved aerated concrete precision blocks, the superior performance and widespread application of precision blocks have been recognized and loved by many construction engineers and designers. Autoclaved aerated concrete blocks, aerated concrete blocks, aerated blocks, aerated bricks, foam bricks, foam forming, light bricks, steam cured aerated blocks, steam cured aerated bricks, etc. are all the same. It&#;s just that different regions have different understandings and titles. Autoclaved aerated concrete blocks are a type of porous concrete block made from fly ash, lime, cement, gypsum, slag, etc.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Job description,　　There are six levels of volumetric density: B, B, B, B, B, and B　　 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.

All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.Where is it, B, B, the distance between the bottom of the wall needs to be filled with small solid bricks and B　　 When laying aerated bricks, but the maximum cannot exceed　　as the main raw materials, 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).Shexian County,　　 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).　　There are seven strength levels: A, A,Shexian CountyAerated block, A, A, A, and A　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.
