　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　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.Daimyo　　Silica sand and slag are ground into slurry with water, then powdered lime, gypsum, and foaming agent are added stirred, and injected into the mold frame　　 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).Tapolca,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 Blocks are classified according to their compressive strength and volumetric density.　　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,DaimyoAerated block, The sound insulation performance is twice that of clay bricks, the impermeability performance is more than twice that of clay bricks, and their overall performance is relatively stable. Even when subjected to strong compression　　 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).demand,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 Blocks are classified according to their compressive strength and volumetric density.　　Control standard for radioactive substances in building materials mixed with industrial waste - Determination of steady-state thermal resistance and related characteristics of insulation materials - Protective hot plate method for testing the performance of aerated concrete - General rules - Test methods for volumetric density, 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

　　Marking examples: strength level A, bulk density level B, superiorInterpretation and observation,　　Marking examples: strength level A, bulk density level B, 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,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added,Daimyoautoclaved aerated concrete block, and processed through batching, mixing, pouring, static stopping, and high-pressure steam curing.
