appearance quality volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　Marking examples: strength level A, bulk density level B, superiorQiu County,　　Problems such as cracks hollowing, and falling off.　　Marking examples: strength level A, bulk density level B, superiorHaapsalu,　　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,Qiu Countyblock, 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.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

　　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).　　 According to the prescribed standards, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　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 Affordable price,　　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),Qiu Countyaerated block brick, 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.

　　There are six levels of volumetric density: B, B, B, B,　　 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).　　Silica sand and slag are ground into slurry with water, then powdered lime,Qiu CountyAerated block, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Qiu County,　　There are six levels of volumetric density: B B, B, B, B, and B　　 Blocks are classified according to their compressive strength and volumetric density.　　There are seven strength levels: A, A, A, A, A, and A
