国家建材局最近确定32家水泥强度检验用标准砂定点经销单位,明确要求对标准砂实施定点经销管理。 长期以来,标准砂经销在从计划经济转向市场经济的过程中,经历了多种经销方式的探索,从多头无序的混乱经销逐渐过渡到统一定点经销,理顺了市场秩序,加强了经销管理, The National Building Materials Bureau has recently identified 32 designated sand distribution and distribution units for cement strength inspections, and has explicitly requested fixed-point distribution management for standard sands.

It has gradually transitioned from disorderly chaotic distribution to a unified fixed-point distribution, rationalized market order, and strengthened distribution management. ,
