Abstrakt: The increasing generation of electronic waste (e-waste) has emerged as a significant environmental challenge globally. This study investigates the feasibility of utilizing e-waste plastic as a partial substitute for coarse aggregate in concrete production. The research evaluates the mechanical properties, durability characteristics, and environmental impact of plastic concrete with varying replacement percentages (10%, 20%, 30%, and 40%) of e-waste plastic. Standard concrete specimens were prepared and tested for compressive strength, tensile strength, flexural strength, and durability parameters including water absorption, chloride penetration, and freeze-thaw resistance. Results indicate that up to 20% replacement of coarse aggregate with e-waste plastic maintains acceptable mechanical properties while providing environmental benefits through waste utilization. The compressive strength decreased by 15.3% at 20% replacement and 28.7% at 30% replacement compared to control specimens. The study demonstrates the potential for sustainable concrete production while addressing the growing e-waste management crisis. [ABSTRACT FROM AUTHOR]
