　　 Blocks are classified according to their compressive strength and volumetric density.　　 Blocks are classified according to their compressive strength and volumetric density.Licheng, Jinan,　　Over centimeters.　　There are seven strength levels: A, A, A, A, A, and ABerlin,　　There are six levels of volumetric density: B, B, B, B, B, and B　　There are seven strength levels: A, A A, A, A,Licheng, Jinanaerated block brick, A, and A　　There are six levels of volumetric density: B, B, B, B, B, and B

　　If the purchasing unit needs other specifications,Licheng, JinanAerated block, they can negotiate with the production factory to determine.　　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 Atechnical service,　　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 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).　　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 　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

　　 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.Highly recommended,　　Marking examples: strength level A, bulk density level B, superior　　 When laying aerated bricks, it is necessary to make batches of poles according to the height of the bricks, and then erect them at the corners of the wall　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification technical requirements, test methods, inspection rules, and transportation of autoclaved aerated concrete blocks.Licheng stacking,Licheng, Jinanautoclaved aerated concrete block, Jinan,　　If the purchasing unit needs other specifications, appearance quality, volumetric density, and compressive strength: excellent product (A) first-class product (B), qualified product (C).
