There are six levels of volumetric density: B, B, B, B, and B If the purchasing unit needs other specifications, Advantages of aerated bricks: Concrete is used as the main raw material for aerated bricks, and then air is added inside, which not only Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Qormi, 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, and compressive strength: excellent product (A), first-class product (B), qualified product (C). as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching mixing, pouring, 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).
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. When constructing aerated bricks, it is required that the mortar strength must meet the design requirements.
