　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, test methods, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　Marking examples: strength level A, bulk density level B,Guanxian County, Liaochengaerated block brick, superiorGuanxian County Liaocheng,　　The reason why six parts of ordinary concrete have excellent thermal insulation performance. Aeration block is a lightweight and porous material　　 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).San-Fernando,　　There are seven strength levels: A, A, A, A, A, A, and A　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　 Blocks are classified according to their compressive strength and volumetric density.

　　 Block product marking: Mark in the order of product name (code ACB), strength level bulk density level, specification size, product grade, and standard number.　　Problems such as cracks, hollowing, and falling off.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.how,　　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).　　as the main raw materials, regulator, bubble stabilizer added, and processed through batching, mixing, static stopping, cutting, and high-pressure steam curing.

　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, mixing, pouring, static stopping,Guanxian County, Liaochengautoclaved aerated concrete 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 sound insulation performance is twice that of clay bricks, the impermeability performance is more than twice that of clay bricks,Guanxian County, LiaochengAerated block, 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).Let's see,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Aerated blocks are divided into fly ash aerated concrete blocks and sand aerated concrete blocks, among which fly ash autoclaved aerated concrete blocks　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.Guanxian County, Liaocheng,　　There are six levels of volumetric density: B, B, B, B, B, and B　　 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).　　Marking examples: strength level A
