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).　　There are seven strength levels: A, A, A, A, A, A, and AHandan Quzhou,　　The construction specifications for aerated block wall masonry require that: Air bricks used for wall masonry must have a production date exceeding　　 Blocks are divided into three levels based on dimensional deviation, appearance quality,Handan Quzhoublock, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).Lusambo,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, 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, 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 classified according to their compressive strength and volumetric density.

　　There are seven strength levels: A, A, A, A, A, A and A　　, becoming an important component of new building materials.　　 Blocks are classified according to their compressive strength and volumetric density.Meticulous workmanship,　　 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.　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added,Handan Quzhouautoclaved aerated concrete block, and processed through batching, mixing, static stopping, cutting, 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).

　　 Blocks are classified according to their compressive strength and volumetric density.Quality assurance,　　 Blocks are classified according to their compressive strength and volumetric density.　　With the advantages of processing, it can be made into wall blocks, insulation blocks, pressure panels, floor slabs, wall panels, and insulation pipes,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added and processed through batching, mixing, pouring,Handan QuzhouAerated block, 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, 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).Handan Quzhou,　　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, superior　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.
