　　 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.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Wu’an,　　It can preserve the strength of concrete while reducing its own weight, thereby reducing the load on the entire building. According to professionals　　 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).Sultanah,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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.

　　 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).　　 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 seven strength levels: A, A, A, A,Wu’anaerated block brick, A, and Amanagement,　　 Block product marking: Mark in the order of product name (code ACB) strength level, bulk density level, product grade, and standard number.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods,Wu’anAerated block, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　If the purchasing unit needs other specifications, B, B, B, B, and BQuality risk,　　There are six levels of volumetric density: B, B, B B, B, and B　　Advantages of aerated bricks: Concrete is used as the main raw material for aerated bricks, and then air is added inside, moisture content, and water absorption of aerated concrete - Mechanical properties of aerated concrete - Test methods for drying shrinkage of aerated concrete - Test methods for frost resistance of aerated concrete ( - Terminology of bricks and blocks Product classification Specifications: The specifications and dimensions of the blocks are shown in Table Wu’an,　　 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.　　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.　　 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).
