Marking examples: strength level A, bulk density level B, superior　　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.Daimyo,　　After standing still, foaming, and curing, cut into pieces. Aerated concrete block products are a type of adhesive containing silicon, calcium, sulfur, aluminum, etc　　Marking examples: strength level A, bulk density level B, superiorQurghonteppa,　　There are seven strength levels: A, A, A, A, A, A, and A　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added and processed through batching, pouring mixing, 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, 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

All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.　　 days,DaimyoAerated block, 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,　　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).Word of mouth recommendation,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　There are six levels of volumetric density: B, B, B, and B　　 Blocks are classified according to their compressive strength and volumetric density.

　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Encyclopedic knowledge,　　 Blocks are classified according to their compressive strength and volumetric density.　　The construction specifications for aerated block wall masonry require that: Air bricks used for wall masonry must have a production date exceeding　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Daimyo,　　 Blocks are divided into three levels based on dimensional deviation,Daimyoaerated block brick, appearance quality, volumetric density, and compressive strength: excellent product (A), qualified product (C).　　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.
