　　If the purchasing unit needs other specifications, they can negotiate with the production factory to determine.　　Marking examples: strength level A, bulk density level B, superiorCongtai,　　 When constructing aerated bricks, it is required that the mortar strength must meet the design requirements.　　There are seven strength levels: A, A A, A, A, A, and ALa-Union,　　 Blocks are classified according to their compressive strength and volumetric density.　　There are seven strength levels: A, A, A, A, A, A, and A　　 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, all versions shown are valid. All standards will be revised, and all parties using this standard should explore the possibility of using the latest versions of the following standards.
