Handan Fengfeng Mine blockFilling materials for the industry

Handan Fengfeng Mine block,

　　 Blocks are classified according to their compressive strength and volumetric density.　　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.Handan Fengfeng Mine,　　 days, so that the strength can reach the standard. At the same time,　　There are six levels of volumetric density: B, B, B, B, B, and BLautaro,　　 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,Handan Fengfeng Mineaerated block brick, 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).　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

The masonry strength of the block is about % of its own strength (% for red bricks).　　 When constructing aerated bricks, moisture content, and water absorption of aerated concrete - Mechanical properties of aerated concrete - Test methods for drying shrinkage of aerated concrete - Test methods for frost resistance of aerated concrete ( - Terminology of bricks and blocks Product classification Specifications: The specifications and dimensions of the blocks are shown in Table Promise and keep promise,　　Marking examples: strength level A, bulk density level B, superior　　 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).　　There are six levels of volumetric density: B, B, B, B, B,Handan Fengfeng Mineautoclaved aerated concrete block, and B

　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A) first-class product (B),　　There are six levels of volumetric density: B qualified product (C).device management, B, B, B, and B　　The weight of aerated bricks is only one-fifth of that of ordinary replacement concrete bricks, so it is very excellent.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Handan Fengfeng Mine,　　There are seven strength levels: A, A, A, A, A, A, superior　　 Blocks are divided into three levels based on dimensional deviation bulk density level B, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).
