摘　　要：介绍了维生素c废母液的产生及特性，综述了以其为原料制备混凝土用高效缓凝剂的方法及其与聚羧酸减水剂复配的应用研究，为维生素C废母液资源化再利用指明了新出路。最后，利用VC废母液与自制聚羧酸系高效减水剂进行复配，净浆流动度测试结果表明，复配减水剂对水泥净浆的流动度保持效果优于单掺聚羧酸系高效减水剂。The origins and characteristics of waste mother liquid of Vitamin C are introduced in the paper. Methods of preparing concrete high range water reducing and retarding admixture with the waste mother liquor and applications of combining it with polycarboxylate superplasticizer are reviewed. Both ways provides new directions for utilization of the waste mother liquid as a resource. Experimental test results show that complex superplastieizer prepared by combination of the waste mother liquid and polycarboxylate superplasticizer has better dispersion retention ability.
