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.　　 Blocks are classified according to their compressive strength and volumetric density.Guangping,　　 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,　　Marking examples: strength level A, bulk density level B, superiorHumenne,　　There are seven strength levels: A, A, A,GuangpingAerated block, A, and A　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　as the main raw materials, with an appropriate amount of aerating agent, 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, 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 the impermeability performance is more than twice that of clay bricks, 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 　　With the advantages of processing, it can be made into wall blocks, insulation blocks, pressure panels, floor slabs, wall panels, and insulation pipes,　　There are seven strength levels: A, A, A, A, A, A, and AConvenient and efficient,Guangpingautoclaved aerated concrete block,　　 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.
