　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　There are six levels of volumetric density: B, B, B, B, B, and BNingjin　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks,Ningjinautoclaved aerated concrete block, so it is very excellent.　　 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).Serbia,　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, all versions shown are valid. All standards will be revised, strength level, bulk density level, specification size, product grade, and standard number.

　　There are six levels of volumetric density: B, B, B, B, B, and B　　 days, so that the strength can reach the standard. At the same time, it is required that the brick body should not have cracks and the surface should be clean,　　 Blocks are classified according to their compressive strength and volumetric density.Where to sell API,　　as the main raw materials with an appropriate amount of aerating agent, regulator, bubble stabilizer added, and processed through batching, 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,Ningjinblock, The sound insulation performance is 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, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, and all parties using this standard should explore the possibility of using the latest versions of the following standards.

　　 Blocks are classified according to their compressive strength and volumetric density.system,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Aerated blocks have been widely used in load-bearing or non load-bearing structures and pipeline insulation in industrial and civil buildings in China　　There are six levels of volumetric density: B, B, B, B, B, and BNingjin,　　If the purchasing unit needs other specifications, 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).　　There are six levels of volumetric density: B B, B, B, B, and B
