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 　　There are seven strength levels: A, A, A, A A, A, and AShen County, Liaocheng,　　Very small, with very good seismic performance.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Keratsini,　　 Blocks are classified according to their compressive strength and volumetric density.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods,Shen County, LiaochengAerated block, inspection rules, product quality instructions, stacking and transportation of autoclaved aerated concrete blocks.　　 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).

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 days, it is required that the brick body should not have cracks and the surface should be clean,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, 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).Information recommendation,　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, all versions shown are valid. All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.　　There are six levels of volumetric density: B, B, B, B and B

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Quotation sheet,　　 Blocks are classified according to their compressive strength and volumetric density.　　Aerated blocks have been widely used in load-bearing or non load-bearing structures and pipeline insulation in industrial and civil buildings in China　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level,Shen County, Liaochengaerated block brick, specification size, product grade, and standard number.Shen County, Liaocheng,　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density,Shen County, Liaochengblock, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard.
