Application progress of scour-abrasion resistant materials of hydraulic concrete

Abstract

As the concrete surfaces of the sluice structure in the water conservancy and hydropower engineering would often suffer from the erosion of high speed sandy flow or water flow with bed load, there will often appear different degrees of wear and cavitations damages after a certain time of operation. Therefore, it is especially important to use the materials with high performance in resisting erosion and abrasion. Based on analyzing the abrasion damage mechanism and form of concrete, this paper mainly summarizes the research and application of scour-abrasion resistant materials, introduces the new development of scour-abrasion resistant materials, and finally provides an effective way of solving the impact of high silt-laden water erosion.
