【摘要】 聚羧酸系高性能减水剂是新型的混凝土外加剂,其掺量小、减水率高、强度高,低碱低氯又环保,已经成功应用于高速铁路、高速公路,在施工部位琐碎、技术要求多的水利工程上也得到了应用。无论是低标号的C30,还是C50的混凝土,应用效果良好,聚羧酸系高性能减水剂完全可以满足混凝土的技术要求,也为今后水利工程外加剂的选择拓宽了范围。更多还原

【Abstract】 High-performance poly carboxylic acid water reducer is a late-model concrete admixture.It has low volume,high slushing rate,high strength,low alkali,low chlorine and beneficial for environment.High-performance poly carbo-xylic acid water reducer has been applied in high-speed railway and super highway.It has also been applied in the parts of trifling construction,serious technical requirements on irrigation works.It has favorable application effects in whatever low grade C30,or concrete C50.High-performance poly carboxylic acid water reducer can content the technical requirements for concrete completely,and also broaden the scope of selecting admixture for irrigation works.更多还原
