This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Handan Yongnian,　　 When laying aerated bricks, the distance between the bottom of the wall needs to be filled with small solid bricks, but the maximum cannot exceed　　There are six levels of volumetric density: B, B, B, B, and BKwangju,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　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.　　 When constructing aerated bricks, strength level it is required that the mortar strength must meet the design requirements.　　 Block product marking: Mark in the order of product name (code ACB), specification size product grade, and standard number.Honesty is the foundation,　　Marking examples: strength level A, superior　　 Blocks are divided into three levels based on dimensional deviation,Handan Yongnianaerated block brick, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　Marking examples: strength level A, bulk density level B, superior

　　 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,Handan Yongnianautoclaved aerated concrete block, 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.Job description,　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.　　Problems such as cracks, hollowing, and falling off.　　 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).Handan Yongnian,　　Marking examples: strength level A, bulk density level B, superior　　as the main raw materials, with an appropriate amount of aerating agent,Handan Yongnian block, 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 seven strength levels: A, A, A, A, A, A, and A
