　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules,Jinan Steel Cityblock, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Jinan Steel City, it can be made into wall blocks, insulation blocks, pressure panels, floor slabs, wall panels, and insulation pipes,　　 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.Harelbeke,　　If the purchasing unit needs other specifications, B, B, B B, and B　　 Blocks are classified according to their compressive strength and volumetric density.

　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, 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).　　The reason why six parts of ordinary concrete have excellent thermal insulation performance. Aeration block is a lightweight and porous material　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added and processed through batching, pouring mixing, static stopping, cutting, and high-pressure steam curing. The unit volume weight of autoclaved aerated concrete blocks is one-third of 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,　　There are seven strength levels: A, A, A, A, A, A, and A　　 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

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Create brilliance　　 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 can be produced using different processes based on material types, quality, and equipment process characteristics. Generally, fly ash or　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A),Jinan Steel Cityautoclaved aerated concrete block, first-class product (B), qualified product (C).Jinan Steel City　　There are six levels of volumetric density: B, B, B, B, B,Jinan Steel Cityaerated block brick, and B　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, and standard number.　　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
