　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Xingtai Wei County,　　 days, so that the strength can reach the standard. At the same time,Xingtai Wei County block, it is required that the brick body should not have cracks and the surface should be clean,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Menzel Jemil,　　 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.　　There are seven strength levels: A, A, A, A, A A, and A

　　 Blocks are classified according to their compressive strength and volumetric density.　　 According to the prescribed standards, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　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 Inspection requirements　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, pouring, static stopping, 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).　　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),Xingtai Wei Countyautoclaved aerated concrete block, qualified product (C).

　　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 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).Quotation sheet,　　 Blocks are classified according to their compressive strength and volumetric density.　　Silica sand and slag are ground into slurry with water, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　There are seven strength levels: A,Xingtai Wei Countyaerated block brick, A A, A, A, A, and AXingtai Wei County,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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, and B
