Performance of retrofitted eccentrically loaded GFRP-reinforced electronic waste concrete components having synthetic fibers

These days, poor electronic waste (E-waste) disposal is polluting the environment and posing health risks in developing nations. Prior research neglected post-damage retrofit efficiency in favor of concentrating on the compressive execution of concrete compressive members reinforced with glass fiber reinforced polymer (GFRP). The purpose of this study is to evaluate the mechanical execution of partly broken and retrofitted electronic waste aggregate concrete (EWC) compressive members that have been reinforced with GFRP helix, bars, and synthetic fibers. Twelve circular specimens measuring 1000 mm in height and 250 mm in diameter were retrofitted quickly using carbon fiber-reinforced polymer (CFRP) sheets. Six specimens had steel bars and helix (SSEWC compressive members) and six specimens had GFRP bars and helix (GSEWC compressive members) for main and transverse reinforcement. CFRP sheets applied for retrofit after load application caused a compressive load-carrying capacity loss of up to 30% in the post-ultimate loading stage. Compressive load-carrying capacity, load-deflection curves, compressive deflection, strength index, stiffness index, ductility index, and crack patterns were assessed pre-and postretrofit for the effects of monotonic axial and eccentric loading, CFRP casing, spiral vertical spacing, synthetic fibers, E-waste concrete, and reinforcement Kind. Comparing the reconstructed SSEWC and GSEWC compressive members to their original counterparts, the results showed improved mechanical execution.
