　　There are six levels of volumetric density: B, B, B, B, B, and B　　There are seven strength levels: A, A, A, A, A, and AJining Zoucheng　　Promoting the application of earth blocks for external wall self insulation, autoclaved sand aerated concrete blocks, and internal partition wall autoclaved sand aerated concrete blocks　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Ar Rutbah,　　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), appearance quality qualified product (C).　　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, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　 The weight of aerated bricks themselves is very light, and their overall performance is relatively stable. Even when subjected to strong compression　　 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.quality standard,　　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.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, inspection rules,Jining Zouchengaerated block brick, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　There are six levels of volumetric density: B, B, B, B, B, and B
