摘要
尽管聚羧酸系减水剂被看作是高性能的、绿色的和最有前途的减水剂品种,但其在实际应用中却暴露出许多较复杂且一时难以解决的技术问题。通过分析聚羧酸系减水剂区别于传统减水剂的性能特点和由此对混凝土性能产生的各种影响,最后就实际工程如何安全高效地应用聚羧酸系减水剂,提出可操作性的合理化建议。
Some complicated problems which can not be easily kept from and solved is exposing when polycarboxylate based superplasticizer （PC） is applied in the concrete constructions on site,although PC is regarded as a high-performance and eco-product based on its high water-reducing rate and high strength-enhancement ability etc.From the aspects of the characteristics of PC compared with those of traditional superplasticizers, and from the aspect of the probable effects of PC on concretes, some proposals are given in order to safely and efficiently apply PC.
