　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　After standing still, foaming, and curing, cut into pieces. Aerated concrete block products are a type of adhesive containing silicon, calcium, sulfur, aluminum, etc　　 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).How many?,　　 Block product marking: Mark in the order of product name (code ACB), strength level, bulk density level, specification size, product grade, and standard number.　　 Blocks are classified according to their compressive strength and volumetric density.　　 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, and all parties using this standard should explore the possibility of using the latest versions of the following standards.
