Utilization of Itakpe Iron ore Tailings in Normal Weight Concrete: An Overview

Abstract

ABSTRACT Some previous studies have reported findings about the possibilities of using Itakpe Iron Ore Tailings (IIOTs) to partially replace sand in the production of concrete. Based on the outcome of previous findings, there is a need for further research to determine the degree of the suitability of using the IIOTs in concrete. This becomes inevitable because some studies reported positive contribution to the properties of concrete while some reported adverse effects. This study highlights the chemical and physical properties of IIOTs as reported by previous studies and compared these properties to those of sand. The properties of fresh and hardened concrete that were produced using IIOTs as partial replacement for sand, as reported in previous works are presented and discussed in this study. Based on the outcome of this study, it has been found that, huge amount of IIOTs is available and there is a need for large volume consumption of the waste material. Discrepancies in the outcomes of previous experimental studies from different researchers also prompted the need for more studies about the use of IIOTs in concrete. If more studies are carried out about the Itakpe Iron ore tailings, the suitability of using it in concrete and the extent of application can be established. Furthermore, there would be sufficient record of researches to back up the findings.
