In this paper, a preliminary study is performed on utilization of copper mine tailings as road base material through geopolymerization. The mine tailings studied is from a copper mine in Arizona, USA and contains mainly silica, alumina and calcium. Sodium hydroxide (NaOH) solution is used as the alkaline geopolymerization agent. Unconfined compression tests are conducted on compacted mine tailings specimens prepared at different NaOH content and cured for different time at room temperature to measure their unconfined compressive strength (UCS). The results show that when an appropriate amount NaOH is used, the strength of compacted mine tailings can be improved. Based on this preliminary study, it can be concluded that mine tailings are a promising road base material if the geopolymerization technology is utilized.
