Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　If the purchasing unit needs other specifications,　　 When constructing aerated bricks, it is required that the mortar strength must meet the design requirements.　　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 Cairns ,　　 Blocks are classified according to their compressive strength and volumetric density.　　There are seven strength levels: A, A,Jinan Shangheblock, A, A, A, A, and A　　 Blocks are divided into three levels based on dimensional deviation, appearance quality,Jinan Shangheaerated block brick, 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, 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.　　 When laying aerated bricks, the distance between the bottom of the wall needs to be filled with small solid bricks, but the maximum cannot exceed　　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 sound insulation performance is 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).property right,　　as the main raw materials, with an appropriate amount of aerating agent, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping cutting, and high-pressure steam curing.
