摘　　要：研究了聚羧酸系减水剂配制的海工自密实高性能混凝土的拌合物性能、抗压强度和抗氯盐侵蚀性能。试验结果表明,四种聚羧酸系高效减水剂与海工自密实高性能混凝土胶凝材料的适应性良好,配制的海工自密实高性能混凝土拌合物性能良好,且具有较高的抗压强度和耐久性,能满足海工混凝土结构耐久性的要求。The workability, compressive strength and chloride resistance of high performance self-compacting concrete for marine structure with polycarboxylate-type superplasticizers are studied. Experimental results show that the adaptability between binder materials of high performance self-compacting concrete for marine structure and four kinds of polycarboxylate-type superplastieizers is good, the properties of concrete mixture are fine, and the compressive strength and chloride resistance are high, which can meet the durability demands of concrete for marine structure.
