Aeration block is a lightweight and porous material　　 Blocks are classified according to their compressive strength and volumetric density.Catory,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, product grade, and standard number.

　　Marking examples: strength level A, bulk density level B, superior　　Due to its high water absorption rate and drying shrinkage rate,plainaerated block brick, 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 Installation requirements,　　 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.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Over centimeters.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size product grade, and standard number.plain,　　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 divided into three levels based on dimensional deviation, appearance quality,plainAerated block, 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.
