Xingtai Qingheaerated block brickWhat are their strengths and advantages

　　There are seven strength levels: A, A, A, A, A, A, and A　　There are six levels of volumetric density: B, B, B, B, and BXingtai Qinghe,　　Aerated blocks, also known as aerated bricks, aerated blocks, aerated concrete blocks, autoclaved aerated concrete blocks, and aerated concrete blocks　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Pyongyang,　　 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.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A), first-class product (B), 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,Xingtai Qingheautoclaved aerated concrete block, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　Location, please note that the maximum distance cannot exceed meters.　　If the purchasing unit needs other specifications they can negotiate with the production factory to determine.Scheme customization,　　 Block product marking: Mark in the order of product name (code ACB), bulk density level, specification size, and standard number.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, first-class product (B) and compressive strength: excellent product (A), 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.
