Aeration block is a lightweight and porous material　　Marking examples: strength level A, bulk density level B, superiorFerkessedougou,　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　Marking examples: strength level A, bulk density level B, superior　　There are seven strength levels: A, A, A, A, A, A, and A

　　Marking examples: strength level A, bulk density level B, superior　　Promoting the application of earth blocks for external wall self insulation, autoclaved sand aerated concrete blocks,JinxiangAerated block, and internal partition wall autoclaved sand aerated concrete blocks　　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.project,　　 Blocks are classified according to their compressive strength and volumetric density.　　 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.　　as the main raw materials, with an appropriate amount of aerating agent,Jinxiangblock, regulator, bubble stabilizer added, 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, and the insulation performance is - times that of clay bricks, 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).Quality Assurance,　　 Blocks are classified according to their compressive strength and volumetric density.　　Silica sand and slag are ground into slurry with water, then powdered lime, gypsum, and foaming agent are added, stirred, and injected into the mold frame　　 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,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules, product quality instructions, and transportation of autoclaved aerated concrete blocks.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density,Jinxiangautoclaved aerated concrete block, and compressive strength: excellent product (A) first-class product (B), qualified product (C).　　 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).
