The mechanical properties and structural features of the M25 grade concrete under changing E-waste content is thoroughly investigated in this work. We investigate the possibilities of using this e-waste material to raise the structural performance and strength of the concrete. Mechanical qualities of the e-waste substituted concrete have been investigated using several tests including compressive strength, tensile strength, and flexional strength. Concrete including 50% e-waste-replaced concrete is more mechanically better than reference control concrete after 28 days of cure. E-waste was used in place of a lot of the concrete, which somewhat degraded mechanical performance. Additionally conducted was a microstructural study to ascertain the e-waste distribution and interaction inside the concrete matrix. Aiming to validate the experimental results, scanning electron microscopy (SEM) and X-ray diffraction (XRD) were employed to evaluate the effect of e-waste on the microstructural properties. The results offer important knowledge on their purpose of improving the performance of M25-grade concrete by proving the way the integration of e-waste alters the microstructure and the mechanical characteristics.
