There are six levels of volumetric density: B, B,Jiaxiangautoclaved aerated concrete block, B, B, B, and B　　 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,JiaxiangAerated block, and all parties using this standard should explore the possibility of using the latest versions of the following standards.Jiaxiang,　　The construction specifications for aerated block wall masonry require that: Air bricks used for wall masonry must have a production date exceeding　　 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).Rousse,　　Marking examples: strength level A, bulk density level B, A, A, A, A,Jiaxiangblock, and A　　 Blocks are classified according to their compressive strength and volumetric density.

　　 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).　　Condensing materials. As the main raw material. This aerated concrete block has the advantages of insulation, moisture resistance, and lightweight.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Superior quality,　　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.　　 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, B, B, B, B, and BPromotion　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　The new building material produced by the aerated block equipment is characterized by light bulk density, high insulation efficiency, good sound absorption, and the ability to　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Jiaxiang,　　There are seven strength levels: A, A, A A, A, A, and A　　 Blocks are classified according to their compressive strength and volumetric density.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B)
