Blocks are classified according to their compressive strength and volumetric density.　　 Blocks are classified according to their compressive strength and volumetric density.Handan Guan Tao,　　Block. And it is required that each design unit should indicate the strength of the materials in the design documents when selecting them,【 Conclusion 】 Although there are differences in the production process and performance between autoclaved aerated concrete blocks and autoclaved aerated concrete precision blocks, the superior performance and widespread application of precision blocks have been recognized and loved by many construction engineers and designers. Autoclaved aerated concrete blocks, aerated concrete blocks, aerated blocks, aerated bricks, foam bricks, foam forming, light bricks, steam cured aerated blocks steam cured aerated bricks, etc. are all the same. It&#;s just that different regions have different understandings and titles. Autoclaved aerated concrete blocks are a type of porous concrete block made from fly ash, lime cement, gypsum, slag, etc.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification,Handan Guan TaoAerated block, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.Zabure,　　Marking examples: strength level A, bulk density level B, superior　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, cutting 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, 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).
