YangguAerated blockThe golden period of building a brand

　　There are six levels of volumetric density: B, B, B, B, B, and B　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Yanggu,　　The reason why six parts of ordinary concrete have excellent thermal insulation performance. Aeration block is a lightweight and porous material　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Kosan-up,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　There are seven strength levels: A, A, A, A, A, A and A　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.

　　as the main raw materials, with an appropriate amount of aerating agent, regulator, and processed through batching, 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, 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).　　Due to its high water absorption rate and drying shrinkage rate, concrete blocks are prone to wall problems after use in construction projects　　 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.Quality assurance,　　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, 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.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification technical requirements,Yangguaerated block brick, test methods, inspection rules, product quality instructions stacking, and transportation of autoclaved aerated concrete blocks.Range,　　 Blocks are classified according to their compressive strength and volumetric density.　　Silica sand and slag are ground into slurry with water, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Yanggu,　　There are six levels of volumetric density: B, B, B, B,Yanggublock,YangguAerated block, B, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).
