Xingtai Neiqiuautoclaved aerated concrete blockCauses of bubbles

　　 Blocks are divided into three levels based on dimensional deviation,Xingtai Neiqiuaerated block brick, 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,　　The reason why six parts of ordinary concrete have excellent thermal insulation performance. Aeration block is a lightweight and porous material　　 Blocks are classified according to their compressive strength and volumetric density.Slobozia,　　Marking examples: strength level A, bulk density level B, A, A, A, A, A, and A　　Specification for autoclaved aerated concrete blocks Scope This standard specifies the product classification, technical requirements test methods, inspection rules, product quality instructions, stacking, and transportation of autoclaved aerated concrete blocks.
