Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, inspection rules,Tai’an Daiyueautoclaved aerated concrete block, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　Marking examples: strength level A, bulk density level B, superiorTai’an Daiyue　　Location, please note that the maximum distance cannot exceed meters.　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, 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).Tiassale,　　 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).　　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 　　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　　With the advantages of processing, insulation blocks, pressure panels, floor slabs, and insulation pipes,　　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.Industry management,　　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.　　 Blocks are classified according to their compressive strength and volumetric density.

　　There are seven strength levels: A, A, A, A, A, A, and Amarket price,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Problems such as cracks, hollowing, and falling off.　　 Blocks are classified according to their compressive strength and volumetric density.Tai’an Daiyue,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Marking examples: strength level A, bulk density level B, superior　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Tai’an DaiyueAerated block, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.
