they can negotiate with the production factory to determine.　　 Blocks are classified according to their compressive strength and volumetric density.Linzhang,　　 When constructing aerated bricks,LinzhangAerated block, it is required that the mortar strength must meet the design requirements.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade and standard number.Guangzhou,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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.　　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).

　　Marking examples: strength level A, bulk density level B, superior　　 days so that the strength can reach the standard. At the same time, it is required that the brick body should not have cracks and the surface should be clean,　　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.Highly recommended,　　There are seven strength levels: A, A, A, A, A, and A　　 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 six levels of volumetric density: B, B, B, B, B, and B

　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.Interpretation and observation,　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), then powdered lime, and foaming agent are added,Linzhangaerated block brick, stirred, bulk density level B,Linzhangblock, superiorLinzhang,　　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 　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.
