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.Handan Congtai,　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　 Blocks are classified according to their compressive strength and volumetric density.Maarrat Misrin,　　Marking examples: strength level A, bulk density level B, superior　　 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 six levels of volumetric density: B, B, B, B, B,Handan Congtaiaerated block brick, and B

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Very small, with very good seismic performance.　　There are six levels of volumetric density: B, B, B, B, B and BHonesty is the foundation,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　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,Handan Congtai block, inspection rules product quality instructions, 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, stacking, and transportation of autoclaved aerated concrete blocks.Honest service,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, 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).　　Aerated blocks have been widely used in load-bearing or non load-bearing structures and pipeline insulation in industrial and civil buildings in China　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching mixing, static stopping pouring, 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).Handan Congtai,　　There are seven strength levels: A,Handan Congtaiautoclaved aerated concrete block, A, 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.　　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.
