Jinan ChangqingAerated blockWhat are the outstanding problems in the industry

　　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 six levels of volumetric density: B, B, B, B, B, and BJinan Changqing,　　Problems such as cracks, hollowing, and falling off.　　 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).Holy-Andre,　　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).　　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).

　　 Blocks are classified according to their compressive strength and volumetric density.Safety production,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade,Jinan Changqingblock, and standard number.　　Block. And it is required that each design unit should indicate the strength of the materials in the design documents when selecting them, aerated concrete blocks the superior performance and widespread application of precision blocks have been recognized and loved by many construction engineers and designers. Autoclaved aerated concrete blocks, aerated blocks, aerated bricks, foam bricks, foam forming, steam cured aerated blocks, steam cured aerated bricks, etc. are all the same. It&#;s just that different regions have different understandings and titles. Autoclaved aerated concrete blocks are a type of porous concrete block made from fly ash, lime, cement,Jinan ChangqingAerated block, gypsum, slag, etc.　　There are seven strength levels: A, A, A A, A, A, and AJinan Changqing,　　Marking examples: strength level A, bulk density level B, superior　　 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.　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements, test methods, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.
