This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Xingtai Qingheblock, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.Xingtai Qinghe, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　There are seven strength levels: A A, A, A, A, A and AKeuru,　　 Blocks are classified according to their compressive strength and volumetric density.　　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.　　 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.

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Due to its high water absorption rate and drying shrinkage rate concrete blocks are prone to wall problems after use in construction projects　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.investment,　　Marking examples: strength level A, bulk density level B, superior　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).　　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

　　 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).Quality inspection report,　　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.　　It is strictly prohibited to use water soaked bricks and bricks that lack water.　　 Blocks are classified according to their compressive strength and volumetric density.Xingtai Qinghe,　　Marking examples: strength level A, bulk density level B, superior　　as the main raw materials, with an appropriate amount of aerating agent,Xingtai QingheAerated block, regulator, bubble stabilizer added,Xingtai Qingheautoclaved aerated concrete block, and processed through batching, pouring, static stopping, 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).　　 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).
