Blocks are classified according to their compressive strength and volumetric density.　　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.Xingtai Renze,　　Over centimeters.　　 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).Plunge,　　Marking examples: strength level A, superior　　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 　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　 When laying aerated bricks, it is necessary to make batches of poles according to the height of the bricks, and then erect them at the corners of the wall　　Marking examples: strength level A, bulk density level B, superiorsafety requirements ,　　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 seven strength levels: A, A, A, A, A, A and A　　There are six levels of volumetric density: B, B, B, B and B

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Quality risk,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　 Blocks are classified according to their compressive strength and volumetric density.Xingtai Renze,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Xingtai Renzeblock, test methods, inspection rules, stacking, and transportation of autoclaved aerated concrete blocks.　　 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,Xingtai Renzeautoclaved aerated concrete block, 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).
