Huge amounts of concrete can be destroyed in various hydraulic structures, involving dams, stilling basins, and spillways, due to the long-term impact of water-borne solids. This phenomenon is mainly caused by the water flowing at high speed that conveyances great quantities of sediments. Furthermore, to the danger of abrasion erosion, there are other issues which are the emissions from cement factories that producing global warming. The utilize of waste material was considered as a technique to minimize the pollution due to the manufacturing of Cement. Geopolymer concrete, manufactured from silica, aluminum, and alkaline activators, can be utilized as a binder to replace Portland cement. Geopolymer technology can decrease global greenhouse emissions created by ordinary Portland cement manufacture. In this study, three different grades of both geopolymer and conventional concrete, 20, 30, and 40 MPa, were prepared and tested abrasion resistance experimentally. The abrasion resistance test was performed using a non-standard device which was a modification of ASTM C1138 (underwater method). The abrasion test was performed at ages of 3, 7, and 28 days. The findings of the tests presented that the geopolymer concrete, was gained its total strength at an early age, as well as the geopolymer concrete had greater abrasion resistance in all three grades than the conventional concrete.
