Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, product grade, and standard number.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A),DaimyoAerated block, first-class product (B), qualified product (C).Daimyo,　　Over centimeters.　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.Mariara,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 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.　　It can preserve the strength of concrete while reducing its own weight, thereby reducing the load on the entire building. According to professionals　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Scheme customization,　　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 　　Marking examples: strength level A, bulk density level B, superior　　as the main raw materials, bubble stabilizer added regulator, 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,Daimyoautoclaved aerated concrete block, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).demand,　　 Blocks are classified according to their compressive strength and volumetric density.　　Starting from January , Huai&#;an City will phase out fly ash aerated concrete in construction projects throughout the city　　Marking examples: strength level A, bulk density level B, superiorDaimyo,Daimyoaerated block brick,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　Marking examples: strength level A, bulk density level B, superior　　 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).
