　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification,Huaiyinaerated block brick, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Huaiyin,　　 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,　　 Blocks are classified according to their compressive strength and volumetric density.Hunedoara,　　 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 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 six levels of volumetric density: B, B, B, B, B, and B

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　With the advantages of processing,HuaiyinAerated block, it can be made into wall blocks, insulation blocks, pressure panels, floor slabs, wall panels, and insulation pipes　　There are seven strength levels: A, A, A, A, A, and Amanagement,　　 Blocks are classified according to their compressive strength and volumetric density.　　There are six levels of volumetric density: B, B, B, B, B, and B　　 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 seven strength levels: A, A, A, A, A 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.　　It can preserve the strength of concrete while reducing its own weight, thereby reducing the load on the entire building. According to professionals　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade and standard number.Huaiyin,　　 Block product marking: Mark in the order of product name (code ACB), strength level, specification size, product grade, and standard number.　　 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.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.
