　　 Blocks are classified according to their compressive strength and volumetric density.　　 When laying aerated bricks, it is necessary to make batches of poles according to the height of the bricks, and then erect them at the corners of the wall　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Service first,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, and standard number.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level,Jizeautoclaved aerated concrete block, specification size, product grade, and standard number.　　 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).

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).
