摘　　要：阐述聚羧酸高效减水剂的特点及其研究和发展的状况;通过水泥净浆流动度试验研究HSP聚羧酸减水剂与基准水泥、粤秀牌P.Ⅱ42.5R硅酸盐水泥和华润牌P.O42.5R普通硅酸盐水泥的适应性;研究HSP聚羧酸减水剂在普通混凝土、泵送混凝土和高性能混凝土中的减水率、保坍效果和工作性;研究HSP聚羧酸减水剂掺量对高性能混凝土力学性能、收缩性能和耐久性的影响。The characteristics, the research and development status of Polycarboxylic high- performance water-reducing agent are expounded. The adaptability of HSP type Polycarboxylic high-performance water-reducing agent to the reference cement, Yuexiu P·Ⅱ42.5R Portland cement, Huarun P·O42.5R ordinary portland cement was researched by the testing of fluidity of cement paste. The water-reducing ratio, slump maintenance and workability of HSP Polycarboxylic high-performance water-reducing agent applied to plain concrete, pumping concrete and high-performance concrete with were researched. The effect of the HSP Polycarboxylic high-performance water-reducing agent on the mechanical properties and durability of high-performance concrete was studied.
