Numerical Investigation of Reinforced Concrete Beam Contain-ing Iron Ore Tailings as Partial Replacement of Sand

Abstract

The production of industrial and agricultural residual byproducts can generate significant environmental impact. In response, researchers have begun incorporating supplementary materials made from agro-industrial wastes to create more sustainable concrete. However, testing the performance of these waste-based concrete mixtures can be time-consuming and expensive. To address this issue, this study utilized three-dimensional non-linear Finite Element simulation using the ABAQUS/CAE software to predict the behaviour of a reinforced concrete beam that incorporated 20% IOT as partial sand replacement. The simulation successfully predicted the damage behaviour of the 20% IOT concrete, indicating the potential of this modelling approach to accurately predict the performance of waste-based concrete mixtures in various designs.
