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.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Jining Zoucheng,　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　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 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).Amersfoort　　There are six levels of volumetric density: B, B, B, B B, and B　　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.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.

　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　Condensing materials. As the main raw material. This aerated concrete block has the advantages of insulation, moisture resistance, and lightweight.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density,Jining Zoucheng block,Jining Zouchengautoclaved aerated concrete block, and compressive strength: excellent product (A), first-class product (B), qualified product (C).Marketing Department,　　 Blocks are classified according to their compressive strength and volumetric density.　　There are seven strength levels: A, A, A, A, and A　　as the main raw materials, with an appropriate amount of aerating agent, regulator,Jining ZouchengAerated block, 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).

　　Marking examples: strength level A, bulk density level B, superiorWhere can I find it?,　　There are seven strength levels: A, A, A, A, A, and A　　Aerated blocks have been widely used in load-bearing or non load-bearing structures and pipeline insulation in industrial and civil buildings in China　　 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, and all parties using this standard should explore the possibility of using the latest versions of the following standards.Jining Zoucheng,　　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.　　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.
