This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 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,Jinan block, 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.Jinan,　　When deformation occurs, during vibration, due to the inertia force of the aerated brick　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Bang Kruai,　　There are seven strength levels: A, A, A, A, A, A, and A　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching 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).　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

　　 Blocks are classified according to their compressive strength and volumetric density.　　The new building material produced by the aerated block equipment is characterized by light bulk density, high insulation efficiency, good sound absorption, and the ability to　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade,JinanAerated block, and standard number.Respect for customers,　　 Blocks are divided into three levels based on dimensional deviation, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　 Blocks are classified according to their compressive strength and volumetric density.　　 Block product marking: Mark in the order of product name (code ACB),Jinanaerated block brick, strength level, bulk density level, specification size, product grade, and standard number.

　　Marking examples: strength level A, bulk density level B, superiorsuperior quality,　　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 　　Over centimeters.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Jinan,　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).　　 Block product marking: Mark in the order of product name (code ACB), strength level bulk density level, product grade specification size, and standard number.　　 Blocks are classified according to their compressive strength and volumetric density.
