Feixiang, HandanAerated blockWhat are the advantages in practical applications

　　 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).　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification technical requirements, test methods, inspection rules, product quality instructions, stacking,Feixiang, Handanautoclaved aerated concrete block, and transportation of autoclaved aerated concrete blocks.Feixiang, Handan,　　 According to the prescribed standards, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　 Block product marking: Mark in the order of product name (code ACB) strength level, bulk density level, specification size,　　There are seven strength levels: A, A, A, A, A, A, 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 　　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.

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules,Feixiang, HandanAerated block, stacking, and transportation of autoclaved aerated concrete blocks.　　With the advantages of processing, it can be made into wall blocks, insulation blocks, pressure panels, floor slabs,Feixiang, Handanblock, wall panels, and insulation pipes,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, 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).Quality assurance,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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).

　　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.Test results,　　 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, all versions shown are valid. All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　 Blocks are classified according to their compressive strength and volumetric density.Feixiang, Handan,　　There are six levels of volumetric density: B, B, B, B B, and B　　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).
