Overpassaerated block brickInspection requirements during installation

　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Marking examples: strength level A, bulk density level B, superiorOverpass,　　 According to the prescribed standards, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, and standard number.Sant Cugat del Valles,　　There are six levels of volumetric density: B, B, B, B, B, they can negotiate with the production factory to determine.　　as the main raw materials, 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).
