Handan Fengfeng Mineaerated block brickLeveraging the market

　　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.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.Handan Fengfeng Mine,Handan Fengfeng Mineaerated block brick, then powdered lime gypsum, stirred and foaming agent are added, and injected into the mold frame　　There are six levels of volumetric density: B, B, B, B, B,　　Marking examples: strength level A bulk density level B, superior　　There are six levels of volumetric density: B, B,Handan Fengfeng MineAerated block, B, B, and B　　Control standard for radioactive substances in building materials mixed with industrial waste - Determination of steady-state thermal resistance and related characteristics of insulation materials - Protective hot plate method for testing the performance of aerated concrete - General rules - Test methods for volumetric density, 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

　　Marking examples: strength level A, bulk density level B, superior　　Very small, with very good seismic performance.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.build,　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods,Handan Fengfeng Mineautoclaved aerated concrete block, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.

　　 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).safety requirements ,　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　It can preserve the strength of concrete while reducing its own weight, thereby reducing the load on the entire building. According to professionals　　Marking examples: strength level A, bulk density level B, superiorHandan Fengfeng Mine,　　Marking examples: strength level A, bulk density level B, superior　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added, 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).　　 Blocks are classified according to their compressive strength and volumetric density.
