Experimental Investigation on E-waste as a Partial Replacement to Fine Aggregate in M50 Grade Concrete

Electronic items that are unwanted, outdated, or expired are referred to as “E-waste” or “E-waste.” They also include materials and chemicals like lead, cadmium, mercury, and beryllium, as well as polymers like polychlorinated biphenyls, polyvinyl chloride, and polystyrene. E-waste presents serious risks to the environment and to people's health. Current procedures concentrate on processing and classifying e-waste carefully in an effort to lessen negative environmental effects and contaminants. E-waste can be used in place of traditional fine aggregate in concrete as a viable solution to the environmental damage E-waste causes. The purpose of this study is to examine the mechanical characteristics of M50 concrete with partial fine aggregate substitution utilizing e-waste and assess its potential to reduce environmental harm. E-waste is replaced with fine aggregate in volumes of 10, 20, and 30%. The specimens of concrete were specifically tested for compressive strength, split tensile strength, and flexural strength. The results obtained from this research demonstrate the significance of e-waste utilization in concrete production. A 10% replacement of e-waste yielded optimum outcomes, showcasing notable improvements in the mechanical properties when compared to the control concrete. The compressive strength exhibited a remarkable increase of 10.24%, while the split tensile strength and flexural strength showed enhancements of 8.93% and 5.36%, respectively. These findings affirm that e-waste can be effectively employed as a substitute material for fine aggregate in concrete. This study proposes a workable option for minimizing the environmental effect of e-waste by integrating e-waste into the manufacturing of concrete, which supports sustainable waste management methods. The research's conclusions highlight how useful E-waste may be as a resource by highlighting how it can be recycled in the desired form while causing the least amount of environmental damage. Implementing e-waste as a substitute material in concrete can enhance its structural performance and simultaneously address the pressing issue of e-waste management.
