Jinan LaiwuAerated blockFeatures and maintenance precautions

　　 Block product marking: Mark in the order of product name (code ACB), bulk density level,Jinan Laiwublock, specification size, product grade, and standard number.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Jinan Laiwu,　　It is strictly prohibited to use water soaked bricks and bricks that lack water.　　 Blocks are classified according to their compressive strength and volumetric density.Krayova,　　as the main raw materials, 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).　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, inspection rules,Jinan Laiwuautoclaved aerated concrete block, product quality instructions, stacking and transportation of autoclaved aerated concrete blocks.　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.

　　Marking examples: strength level A, bulk density level B, superior　　 According to the prescribed standards, the thermal conductivity of qualified aerated bricks is generally between . and .W/mK　　 The following standards contain provisions that constitute the provisions of this standard by reference in this standard.

　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification,Jinan LaiwuAerated block, technical requirements, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.Inspection environment,　　 Blocks are classified according to their compressive strength and volumetric density.　　It can preserve the strength of concrete while reducing its own weight, thereby reducing the load on the entire building. According to professionals　　If the purchasing unit needs other specifications, volumetric density, and compressive strength: excellent product (A), first-class product (B), qualified product (C).　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　There are seven strength levels: A, A, A, A, A, A, and A
