　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements test methods, inspection rules, stacking, and transportation of autoclaved aerated concrete blocks.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Shahe,　　 When laying aerated bricks, it is necessary to make batches of poles according to the height of the bricks, and then erect them at the corners of the wall　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Pombal,　　There are six levels of volumetric density: B, B, B B, B and B　　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 　　There are six levels of volumetric density: B, B, B, B, B, and B

　　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).　　Over centimeters.　　 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).Quality department, technical requirements, test methods, inspection rules, product quality instructions, stacking,Shaheautoclaved aerated concrete block, and transportation of autoclaved aerated concrete blocks.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality,ShaheAerated block, volumetric density, and compressive strength: excellent product (A), qualified product (C).　　There are seven strength levels: A, A, A, A, A,Shahe block, and A

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Safety and health,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　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　　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 Shahe,　　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, and compressive strength: excellent product (A) volumetric density, first-class product (B), qualified product (C).　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.
