There are six levels of volumetric density: B,Dongablock, B B, B, B, and B　　Marking examples: strength level A, bulk density level B, superiorDonga,　　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,Dongaaerated block brick, foam bricks, foam forming, light bricks, 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, gypsum, slag, etc.　　 Blocks are divided into three levels based on dimensional deviation, appearance quality, volumetric density, and compressive strength: excellent product (A),Dongaautoclaved aerated concrete block, first-class product (B), qualified product (C).Ash on the arzette,　　 Blocks are classified according to their compressive strength and volumetric density.　　There are seven strength levels: A, A, A, A, A, A, and A　　Marking examples: strength level A, bulk density level B, superior
