聚羧酸系高性能减水剂的性能及应用研究

Performance of Polycarboxylate High Performance Water Reducer and Its Application

研究了聚羧酸高性能减水剂的性能及在混凝土中的应用。经实验证实,聚羧酸系高性能减水剂可以用来配制C30～C80商品泵送混凝土、80小时超缓凝商品泵送混凝土和具有高耐久性的海工混凝土。

Study was made of the performance of polycarboxylate water reducer an d its application to concrete. Experimental tests showed that polycarboxylate wa ter reducer could be used to prepare C30~C80 ready-mixed pumping concretes, supe r retarding ready-mixed pumping concretes with a retarding period of 80 hrs and marine concretes with high durability.
