Utilisation of iron ore tailings as aggregates in concrete

ers who are into iron ore mining. This study seeks to add value to the tailings by utilis-ing 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 ...
