The following standards contain provisions that constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, and all parties using this standard should explore the possibility of using the latest versions of the following standards.　　Marking examples: strength level A, bulk density level B, superiorHandan Cheng’an,　　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, cutting, and high-pressure steam curing. The unit volume weight of autoclaved aerated concrete blocks is one-third of 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).Chinhoyi　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density,Handan Cheng’anblock, and compressive strength: excellent product (A), qualified product (C).　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification,Handan Cheng’anaerated block brick, 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
