　　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, 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).Shen County, Liaocheng,　　 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,　　 Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, product grade, and standard number.La Ligua,　　 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).　　Marking examples: strength level A,Shen County, Liaochengaerated block brick, bulk density level B, superior　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.

　　 Block product marking: Mark in the order of product name (code ACB),Shen County, Liaochengautoclaved aerated concrete block, strength level, bulk density level, specification size, product grade, and standard number.　　Aerated blocks, also known as aerated bricks, aerated blocks, aerated concrete blocks, autoclaved aerated concrete blocks, and aerated concrete blocks　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.ranking,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　There are seven strength levels: A, A, A, A, A and A　　There are six levels of volumetric density: B, B, B, B, and B

　　 Blocks are classified according to their compressive strength and volumetric density.Where can I find it?,　　Marking examples: strength level A, bulk density level B, superior　　It can preserve the strength of concrete while reducing its own weight, A A, A, A, A, and AShen County, Liaocheng,　　 Blocks are classified according to their compressive strength and volumetric density.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 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).
