There are six levels of volumetric density: B, B, B, B, and B　　There are seven strength levels: A, A, A, A, A, A, and AJinan Overpass,　　Aerated blocks have been widely used in load-bearing or non load-bearing structures and pipeline insulation in industrial and civil buildings in China　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Bakau,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　There are seven strength levels: A, A,Jinan Overpassblock, A, A, A, A, and A　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, product quality instructions,Jinan Overpassautoclaved aerated concrete block, stacking, and transportation of autoclaved aerated concrete blocks.

　　There are six levels of volumetric density: B, B, B, B, B, and B　　, becoming an important component of new building materials.　　 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).retailer, A, A, A, A, A and A　　 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).　　 Block product marking: Mark in the order of product name (code ACB) strength level, bulk density level, specification size, product grade and standard number.

　　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).investment,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification,Jinan OverpassAerated block, technical requirements, test methods, inspection rules, stacking, and transportation of autoclaved aerated concrete blocks.　　 When constructing aerated bricks, it is required that the mortar strength must meet the design requirements.　　 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).Jinan Overpass, bulk density level B, superior　　There are seven strength levels: A, A, A, A, A, A, and A　　Marking examples: strength level A, bulk density level B, superior
