　　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.　　Aerated blocks, aerated blocks, aerated concrete blocks, autoclaved aerated concrete blocks,Jinxiang, JiningAerated block,　　as the main raw materials and all parties using this standard should explore the possibility of using the latest versions of the following standards.Welcome calls , with an appropriate amount of aerating agent, regulator, bubble stabilizer added,Jinxiang, Jining 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).　　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
