　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Very small with very good seismic performance.　　Marking examples: strength level A,Ningjin block, bulk density level B,　　 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.　　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,Ningjinaerated block brick, and compressive strength: excellent product (A), first-class product (B), qualified product (C).

　　Marking examples: strength level A, bulk density level B, superiorHow much is it,　　Marking examples: strength level A bulk density level B, superior　　Blocks can be produced using different processes based on material types, quality, and equipment process characteristics. Generally, fly ash or　　as the main raw materials, 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 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).Ningjin,　　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,NingjinAerated block, 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 A　　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
