Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, product grade, and standard number.　　There are six levels of volumetric density: B, B, B, B, B, and Bplain,plainautoclaved aerated concrete block,　　 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,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Magnifier,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 Blocks are classified according to their compressive strength and volumetric density.　　 Blocks are classified according to their compressive strength and volumetric density.

　　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 　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks,　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density,plain block, 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 　　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).
