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 six levels of volumetric density: B, B, B, B, B, and BJining Sishui,　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level,Jining Sishuiautoclaved aerated concrete block, specification size product grade, and standard number.Burunday,　　 Blocks are classified according to their compressive strength and volumetric density.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, first-class product (B), qualified product (C).　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.

　　as the main raw materials, with an appropriate amount of aerating agent,Jining SishuiAerated block, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, 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).　　 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,　　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.Encyclopedic knowledge,　　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, A they can negotiate with the production factory to determine.　　There are seven strength levels: A, A, A, A, and A
