Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Jining,　　Block. And it is required that each design unit should indicate the strength of the materials in the design documents when selecting them, 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,JiningAerated block, 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.　　 Block product marking: Mark in the order of product name (code ACB) strength level, bulk density level, specification size, product grade, and standard number.Pozarewatz,　　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, 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).　　as the main raw materials, with an appropriate amount of aerating agent, regulator,Jiningblock, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping, cutting, and high-pressure steam curing.
