  • Utilization of iron ore tailings as fine aggregate in

    · Iron ore tailings have the potential to be used as fine aggregate because they are relatively inert and the particle size of the tailings is significantly larger than that of cement This paper investigated the use of iron ore tailings to replace natural sand as fine aggregate and studied the impact that various replacement levels had on the mechanical properties of UHPC Additionally, theIron ore tailings are a common type of hazardous solid waste in China and have caused serious environmental problems, and the high cost of producing ultrahigh performance concrete (UHPC) provides the motivation to look for lowpriced raw materials In this paper, the possibility of using iron ore tailings to replace natural aggregate to prepare UHPC under two different curing regimes wasUtilization of iron ore tailings as fine aggregate in· Utilization of iron ore tailings as fine aggregate in ultrahigh performance concrete Constr Build Mater, 50 (2014), pp 540548 Article Download PDF View Record in Scopus Google Scholar EA Uchechukwu, MJ Ezekiel Evaluation of the iron ore tailings from Itakpe in Nigeria as concrete material Adv Mater, 3 (4) (2014), p 27 CrossRef View Record in Scopus Google ScholarEvaluation of iron ore tailings as replacement for fine
