Utilisation Of Iron Ore Tailings As Aggregates In Concrete, Francis Atta Kuranchie, Sanjay Kumar Shukla, Daryoush Habibi, Alireza Mohyeddin

Research outputs 2014 to 2021

Sustainable handling of iron ore tailings is of prime concern to all stakeholders who are into iron ore mining. This study seeks to add value to the tailings by utilising them as a replacement for aggregates in concrete. A concrete mix of grade 40 MPa was prepared in the laboratory with water–cement ratio of 0.5. The concrete were cured for 1, 2, 3, 7, 14 and 28 days. The properties of the concrete such as workability, durability, density, compressive strength and indirect tensile strength were tested. A controlled mix of concrete was also prepared in similar way using conventional materials …
