　　 Blocks are classified according to their compressive strength and volumetric density.　　The new building material produced by the aerated block equipment is characterized by light bulk density, high insulation efficiency, good sound absorption, and the ability to　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, and standard number.Highly recommended,　　 Block product marking: Mark in the order of product name (code ACB), strength level,Guanxian County, Liaocheng block,Guanxian County, Liaochengaerated block brick, bulk density level, specification size, product grade, and standard number.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　There are seven strength levels: A, A, A, A, A, A, and A

　　Marking examples: strength level A, bulk density level B, superiorProduct line,　　There are seven strength levels: A, A, A, A, A, and A　　When deformation occurs, it will not damage the internal structure. In addition, during vibration, due to the inertia force of the aerated brick　　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).Guanxian County, Liaocheng,　　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.
