As the concrete surfaces of sluice structure in water conservancy and hydropower project of?ten suffer from the erosion of high speed sandy flow or water flow with bed load, wear and cavitations damages of different degrees can always be found after a certain time of operation. Therefore, it is impor?tant to use the materials with high performance in resisting erosion and abrasion. In this paper, tests of mixing ratio and performance of the high elastic mortar were presented, which showed the characteris?tics and advantages of this material. Based on the outdoor test, construction technologies of the high elas?tic mortar was summarized, which provided a new material selection for repairing the concrete damages due to erosion and abrasion.
