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.　　Marking examples: strength level A, bulk density level B, superiorJinan Changqing,　　With the advantages of processing, it can be made into wall blocks, insulation blocks, pressure panels, wall panels, and insulation pipes,　　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 Satipo,　　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, 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.　　There are six levels of volumetric density: B, B, B, B, B, and B

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions,Jinan Changqing block, stacking, and transportation of autoclaved aerated concrete blocks.　　Problems such as cracks, hollowing, and falling off.　　There are seven strength levels: A, A, A A, A, A, and AInspection standard, they can negotiate with the production factory to determine.

　　 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.Service first,　　 Block product marking: Mark in the order of product name (code ACB), strength level bulk density level,Jinan Changqingaerated block brick, specification size, product grade, with very good seismic performance.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Jinan Changqing,　　 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).　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification,Jinan ChangqingAerated block, technical requirements, test methods, inspection rules product quality instructions, 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
