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,Longyao block, 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, inspection rules, stacking, and transportation of autoclaved aerated concrete blocks.Longyao,　　Starting from January , , Huai&#;an City will phase out fly ash aerated concrete in construction projects throughout the city　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density,Longyaoautoclaved aerated concrete block, and compressive strength: excellent product (A) first-class product (B), qualified product (C).Pobe,　　 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).　　 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

　　Marking examples: strength level A, bulk density level B, superior　　It can preserve the strength of concrete while reducing its own weight, thereby reducing the load on the entire building. According to professionals　　There are seven strength levels: A, A, A, A, A, A, and AManagement Department,　　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 　　There are seven strength levels: A, 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).
