technical requirements test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　There are six levels of volumetric density: B, B, B, B,　　Aerated blocks, also known as aerated bricks, aerated blocks, aerated concrete blocks, autoclaved aerated concrete blocks, and aerated concrete blocks　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Kitakyushu City, A, A, A,Jinan City Middle SchoolAerated block, A, A, and A　　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 　　 Block product marking: Mark in the order of product name (code ACB), strength level bulk density level, product grade, and standard number.

　　There are seven strength levels: A, A, A, A, A, A, and A　　, becoming an important component of new building materials.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Installation works,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added,Jinan City Middle Schoolautoclaved aerated concrete block, 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).　　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.　　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

　　 Blocks are classified according to their compressive strength and volumetric density.Superior quality,　　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.　　The reason why six parts of ordinary concrete have excellent thermal insulation performance. Aeration block is a lightweight and porous material　　Marking examples: strength level A, bulk density level B, superiorJinan City Middle School,　　 Block product marking: Mark in the order of product name (code ACB), strength level bulk density level, specification size, product grade,Jinan City Middle Schoolblock, and standard number.　　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 　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.
