Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B),Shaheblock, qualified product (C).　　 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,ShaheAerated block, and all parties using this standard should explore the possibility of using the latest versions of the following standards.Shahe,　　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　　 Blocks are classified according to their compressive strength and volumetric density.Hongsong,　　There are seven strength levels: A, A, A, A, A, A, and A　　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. 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).　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

　　There are six levels of volumetric density: B, B, B,Shaheaerated block brick, B, B, and B　　 The weight of aerated bricks themselves is very light, and their overall performance is relatively stable. Even when subjected to strong compression　　There are six levels of volumetric density: B, B, B, B, B, and BSales Department,　　 Blocks are classified according to their compressive strength and volumetric density.　　There are seven strength levels: A, A, A, A, A, A, and A　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.
