NUMERICAL INVESTIGATION OF REINFORCED CONCRETE BEAM CONTAINING IRON ORE TAILINGS AS PARTIAL REPLACEMENT OF SAND

Abstract

Abstract

The production of industrial and agricultural residual byproducts can generate significant environmental impact. In response, incorporating supplementary materials made from agro- industrial wastes to create more sustainable concrete is being undertaken. However, testing the performance of these waste-based concrete mixtures can be time-consuming and expensive. To resolve this problem, this study utilized three-dimensional non-linear Finite Element simulation using the ABAQUS/Computer Aided Engineering software/ to predict the behavior of a reinforced concrete beam that incorporated 20% IOT as partial sand replacement. The ultimate load obtained from the 20% IOT concrete beam was compared with experimental results, which showed a 19% positive difference in terms of the load-carrying capacity. Hence, the simulated experiments successfully predicted the damage behavior of the 20% IOT concrete, indicating the potential of this modeling approach to accurately predict the performance of waste-based concrete mixtures in various designs.
