　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements,Laiwu prefecture level city in Shandongautoclaved aerated concrete block, test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.　　 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).Laiwu prefecture level city in Shandong,　　It is strictly prohibited to use water soaked bricks and bricks that lack water.　　There are six levels of volumetric density: B, B, B, B, and BRotorua,　　 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.　　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, stacking, and transportation of autoclaved aerated concrete blocks.
