Utilization of E-Waste as Coarse Aggregates in Geopolymer Concrete

Abstract

E-waste is a general term for damaged, surplus, or excess electrical and electronic equipment. Due to quick technological advancement and inexpensive beginning costs, there is a rapidly expanding global surplus of e-waste. If not managed appropriately, the many sorts of compounds and chemicals included in e-waste can seriously harm both human health and the environment. Large volumes of e-waste may be recycled in the concrete sector, solving both the disposal and reuse issues. The most practical application of e-waste is thus thought to be recycling and reuse in the geopolymer concrete (GPC) industry. The experimental study is carried out to enhance the mechanical properties of the GPC (M30 Grade) with varies percentage e-waste replacement for coarse aggregates by casting cubes, cylinders, and beams. Also, an empirical regression-based model is also formulated for the evaluation of the strength of GPC at varying e-waste coarse aggregate (EWCA) percentages.
