Abstract：To improve the durability of concrete materials in water conservancy engineering construction and reduce the usage ofsand raw materials，steel slag was used to replace part of the standard sand to prepare a kindof impermeable concrete in the experiment，and studies wereconductedonits dry-wet resistance，freze resistance，impermeabilityas wellas theconstruction technologyapplied in water conservancy construction.Theresultsshowed that the impermeable concrete achieved the optimal durability when the replacement rate of steel slag was 20% . At this replacement rate，the mass loss rate of the concrete was 0.82% and the corrosion resistance coefficient was O.75 after 40 dry-wet cycles in sodium sulfate solution，and its mass loss rate was -0.21% after 100 freeze-thaw cycles.In addition，the concrete exhibited excellent impermeability with a water pressure penetration value of 0.88MPa ：
