A, A, A, A, A, and A　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, and transportation of autoclaved aerated concrete blocks.Jining Wenshang stacking,　　Starting from January , , Huai&#;an City will phase out fly ash aerated concrete in construction projects throughout the city　　Marking examples: strength level A, bulk density level B, superiorGenet,　　There are six levels of volumetric density: B, B, B, B, B,Jining WenshangAerated block, and B　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).　　There are seven strength levels: A, A, A, A, A, A, and A

　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).　　 days, 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,　　Marking examples: strength level A, bulk density level B, superiorSuperior quality,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　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 　　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.

　　Marking examples: strength level A, bulk density level B, superiorHonesty is the foundation,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Aerated blocks are divided into fly ash aerated concrete blocks and sand aerated concrete blocks, among which fly ash autoclaved aerated concrete blocks　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, 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).Jining Wenshang,　　 Block product marking: Mark in the order of product name (code ACB) strength level, bulk density level, specification size, product grade, and standard number.　　There are seven strength levels: A, A A, A, A, A, and A　　There are six levels of volumetric density: B, B, B, B, B, and B
