　　There are six levels of volumetric density: B, B, B, B, and B　　It is strictly prohibited to use water soaked bricks and bricks that lack water.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.Industry management,　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, 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,Jining Renchengautoclaved aerated concrete block, 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).　　 Blocks are divided into three levels based on dimensional deviation,Jining RenchengAerated block, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　There are six levels of volumetric density: B, B, B, B, B, and B
