　　 Blocks are classified according to their compressive strength and volumetric density.　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.Xingtai Ningjin　　Aerated blocks, also known as aerated bricks, aerated concrete blocks, autoclaved aerated concrete blocks, and aerated concrete blocks　　There are six levels of volumetric density: B, B, B, B,Xingtai Ningjinaerated block brick, B, and BTsumeb,　　There are six levels of volumetric density: B, B, B, B, B, and B　　This standard applies to autoclaved aerated concrete blocks (hereinafter referred to as blocks) used for walls and insulation in civil and industrial buildings.　　 Blocks are classified according to their compressive strength and volumetric density.

　　 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).　　 The weight of aerated bricks themselves is very light, and their overall performance is relatively stable. Even when subjected to strong compression　　 Blocks are classified according to their compressive strength and volumetric density.build,　　There are six levels of volumetric density: B, B, B, B, B, strength level, bulk density level, specification size,Xingtai NingjinAerated block, product grade, and standard number.　　 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).
