Evaluation of the Structural Response of Reinforced Concrete Beams Produced with River Gravel as Coarse Aggregate in Building Construction

Abstract

An increase in demand for concrete to meet global needs has been accompanied by an increase in global concerns due to an increase in demand for the non-renewable resources that are and comprise the constituents of concrete. To address these concerns and mitigate the impact of their depletion, researchers have investigated the intrinsic properties of a wide range of available materials and assessed their contribution when mixed with concrete. This paper presents the findings of an experimental study that was carried out to assess the structural response of concrete beams made with river gravel as coarse aggregate. Six reinforced beams (100 x 150 x 1100 mm) and six cubes were cast to investigate the specimens' flexural and compressive behavior. The failure modes, bending, and shear capacity were investigated in this study. According to the findings of the study, river gravel used as coarse aggregate in concrete has a roughly equivalent or slightly lower structural performance than conventional coarse aggregate, indicating the feasibility of river gravel as coarse aggregate for building construction.
