Ningyangaerated block brickProduct differentiation method

　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A),NingyangAerated block, first-class product (B), qualified product (C).Ningyang,　　Over centimeters.　　There are six levels of volumetric density: B, B, B, B, B, and BEl Obeid,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification technical requirements, inspection rules,Ningyangblock, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　 Blocks are classified according to their compressive strength and volumetric density.　　 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.

　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　Very small, with very good seismic performance.　　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 Sincere service, 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.　　 Blocks are classified according to their compressive strength and volumetric density.　　 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, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.Good quality,　　 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.　　Very small, with very good seismic performance.　　 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).Ningyang,　　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,Ningyangautoclaved aerated concrete block, 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).　　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 　　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.
