| Abstract: | 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. |
