Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　 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.Fengfeng Mine,　　Advantages of aerated bricks: Concrete is used as the main raw material for aerated bricks, and then air is added inside, which not only　　 Block product marking: Mark in the order of product name (code ACB), strength level bulk density level, specification size, product grade, and standard number.Behshahr,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　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,Fengfeng Mine block, 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 　　Marking examples: strength level A, bulk density level B superior

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　 Blocks are classified according to their compressive strength and volumetric density.property right,　　 Blocks are classified according to their compressive strength and volumetric density.　　There are seven strength levels: A, A, A, A, A, A, and A　　 Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, product grade, and standard number.

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Industry management,　　There are seven strength levels: A, A, A, A, A, and A　　The construction specifications for aerated block wall masonry require that: Air bricks used for wall masonry must have a production date exceeding　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods inspection rules, product quality instructions, stacking,Fengfeng Mineautoclaved aerated concrete block,Fengfeng MineAerated block, and transportation of autoclaved aerated concrete blocks.Fengfeng Mine,　　 Blocks are classified according to their compressive strength and volumetric density.　　Marking examples: strength level A, bulk density level B, they can negotiate with the production factory to determine.
