　　 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).　　 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,Xingtai Juluautoclaved aerated concrete block, 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.Xingtai Julu,　　Over centimeters.　　 Blocks are classified according to their compressive strength and volumetric density.Mehtar Lam , strength level, bulk density level, specification size, product grade, and standard number.　　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 　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification technical requirements, inspection rules test methods, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.

　　There are six levels of volumetric density: B B, B, B, B, and B　　After standing still, foaming and curing, cut into pieces. Aerated concrete block products are a type of adhesive containing silicon, calcium, sulfur, aluminum, etc　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Where is it,　　as the main raw materials, with an appropriate amount of aerating agent,Xingtai Juluaerated block brick, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, 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).　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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, superiordiscount,　　There are seven strength levels: A, A, A, A, A, A,Xingtai Julu block, and A　　 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, B, B, B, B, and BXingtai Julu,　　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 　　 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.
