　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Block. And it is required that each design unit should indicate the strength of the materials in the design documents when selecting them,【 Conclusion 】 Although there are differences in the production process and performance between autoclaved aerated concrete blocks and autoclaved aerated concrete precision 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 concrete blocks, aerated blocks, aerated bricks, foam bricks, light bricks, 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,Handan LinzhangAerated block, lime, cement, gypsum, slag, etc.　　Marking examples: strength level A bulk density level B, superiorquality index,　　Marking examples: strength level A, bulk density level B, superior　　There are six levels of volumetric density: B, B,Handan Linzhang block, B, B, B, and B　　There are six levels of volumetric density: B, B, B, B, B, and B
