Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Handan and Hanshanaerated block brick, test methods, inspection rules, stacking, and transportation of autoclaved aerated concrete blocks.　　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 Handan and Hanshan,　　It is strictly prohibited to use water soaked bricks and bricks that lack water.　　Marking examples: strength level A, bulk density level B, superiorCarley,　　There are seven strength levels: A, A, A, A, A, A, and A　　Marking examples: strength level A, bulk density level B, superior　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.

　　 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).　　It can preserve the strength of concrete while reducing its own weight, thereby reducing the load on the entire building. According to professionals　　 Blocks are divided into three levels based on dimensional deviation,Handan and Hanshanautoclaved aerated concrete block, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).ranking,　　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.　　 Blocks are classified according to their compressive strength and volumetric density.

　　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 average method,　　Marking examples: strength level A, bulk density level B, superior　　Condensing materials. As the main raw material. This aerated concrete block has the advantages of insulation, moisture resistance, and lightweight.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Handan and Hanshan,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　as the main raw materials, with an appropriate amount of aerating agent, regulator bubble stabilizer added, mixing, pouring, cutting,Handan and Hanshan block, 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.
