| Abstract: | The concrete with high volume mineral admixture,adding superplasticizer,composite of different species and different content of the retarder,is studied on the workability,setting time,different age strength of concrete.Tests show that adding different species and fixed content of the retarder can improve the workability of concrete,extend the setting time of concrete,increase the late age strength of concrete. |

| Keywords: | retarder summer construction high volume mineral admixture setting time strength |
