摘　　要：混凝土强效剂是一种新型混凝土外加剂。研究了混凝土强效剂对聚羧酸减水剂饱和点掺量的影响，以及在不同等级混凝土中的技术应用和经济效益分析。结果表明：强效剂掺量在0．6％，可以提高聚羧酸减水剂的饱和点掺量；在减少10％～15％水泥用量时，混凝土和易性得到改善，3、7、28d强度均满足设计要求；同时具有可观的经济和环境效益。Concrete potent additive is a new kind of concrete admixture.lnfluence on saturation point ofpolycarboxylate superplasticizer with concrete potent additives, the technology and economic analysis for different levels of concrete were investigated in this paper.The re- suits show that when the dosage of concrete potent additives is in 0.6% ,it can increase the saturation point of polycarboxylate superplasti- cizer dosage.When the reduction of cement is 10% to 15%, the workability of concrete was improved, the design requirements 3,7,28 d of concrete strength was satisfied.Also the economic and environmental benefits are considerable.
