Lichengaerated block brickThe flourishing development of processing

　　 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).　　as the main raw materials, with an appropriate amount of aerating agent, regulator, bubble stabilizer added,Lichengaerated block brick, and processed through batching, pouring, 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).Licheng,　　Advantages of aerated bricks: Concrete is used as the main raw material for aerated bricks, and then air is added inside, which not only　　 Blocks are classified according to their compressive strength and volumetric density.Puerto-Cabezas,　　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, 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 　　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.

　　 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).　　Location, please note that the maximum distance cannot exceed meters.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.original,　　Marking examples: strength level A, bulk density level B, superior　　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 　　There are six levels of volumetric density: B, B, B B,LichengAerated block,Lichengautoclaved aerated concrete block, B, 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), qualified product (C).Fair price,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　Problems such as cracks, hollowing, and falling off.　　 Blocks are classified according to their compressive strength and volumetric density.Licheng,　　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).　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.
