　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　There are seven strength levels: A, A, A, A A, A, and AHonest service,　　There are six levels of volumetric density: B, B, B, B, B, and B　　Marking examples: strength level A,Dongpingaerated block brick, bulk density level B, superior　　 Blocks are classified according to their compressive strength and volumetric density.

　　There are seven strength levels: A, A, A, A, A, and ADiscount,　　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 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,Dongpingblock, 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).　　Condensing materials. As the main raw material. This aerated concrete block has the advantages of insulation, moisture resistance, and lightweight.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Dongping,　　Marking examples: strength level A, bulk density level B, superior　　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 　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.
