Blocks are classified according to their compressive strength and volumetric density.　　Marking examples: strength level A, bulk density level B, superiorXintai,　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　There are six levels of volumetric density: B, B, B, B, B, and BIdenao,　　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,Xintaiautoclaved aerated concrete block, 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).　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, first-class product (B), qualified product (C).　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　Marking examples: strength level A, bulk density level B, superior　　 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　　There are seven strength levels: A, A, A, A, A, A, and Aindex,　　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 classified according to their compressive strength and volumetric density.　　 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, 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 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).Service first,　　There are six levels of volumetric density: B, B, B, B, B, and B　　The reason why six parts of ordinary concrete have excellent thermal insulation performance. Aeration block is a lightweight and porous material　　as the main raw materials with an appropriate amount of aerating agent, bubble stabilizer added regulator, and processed through batching, mixing, static stopping,Xintai block,XintaiAerated block, 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 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).Xintai,　　There are six levels of volumetric density: B, B, B, B, B, and B　　 Blocks are classified according to their compressive strength and volumetric density.　　Marking examples: strength level A, superior
