　　 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.　　There are seven strength levels: A, A A, A,Xiajinaerated block brick, A, A, and AXiajin,　　Silica sand and slag are ground into slurry with water, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Touggourt,　　 Blocks are classified according to their compressive strength and volumetric density.　　 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,XiajinAerated block, and B

　　Marking examples: strength level A bulk density level B, superior　　It is strictly prohibited to use water soaked bricks and bricks that lack water.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B),　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification,Xiajinautoclaved aerated concrete block, technical requirements, test methods inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　There are seven strength levels: A, A, A, A, A, A, and A　　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
