　　Marking examples: strength level A, superior　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.Jinan Laiwu,　　 According to the prescribed standards, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　There are six levels of volumetric density: B, B, B, B B, and BVinh,　　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, 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 seven strength levels: 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), first-class product (B), qualified product (C).

　　There are six levels of volumetric density: B, B, B, B, B, and B　　When deformation occurs,Jinan Laiwublock, it will not damage the internal structure. In addition, during vibration, due to the inertia force of the aerated brick　　Marking examples: strength level A, bulk density level B, bulk density level B　　Marking examples: strength level A, superior　　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, 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 　　Marking examples: strength level A bulk density level B, superior
