摘　　要：减水剂的性能一般都较单一,在实际工程应用时,都要与缓凝剂、引气剂等外加剂进行复合。试验表明:采用复合功能型聚羧酸高性能减水剂配制的混凝土具有流动性好、坍落度损失小、不泌水、硬化混凝土强度比高等特点。The performance of water-reducing admixtures is generally single. In practical application, it must be com pounded with retarding admixtures, air entraining admixtures, ect. The experiment showed that used compounded functional polycarboxylate type high performance water-reducing admixtures, the concrete has good flowability, few slump loss,no bleeding,high ratio of compressive strength.
