This study explores the viability of integrating waste plastic materials as a partial substitute for fine aggregate in concrete, aiming to mitigate environmental concerns while potentially enhancing concrete properties. Through various laboratory experiments, including normal consistency tests and slump cone tests, the research evaluates the effects of waste plastic on concrete characteristics. Findings indicate that the addition of waste plastic has negligible impacts on concrete setting time, but it reduces workability as plastic content increases, potentially leading to bleeding or segregation. Compressive strength tests reveal a decline in strength at 14 days for concrete containing 10% and 15% waste plastic, accompanied by decreasing densities with higher plastic content. Nonetheless, incorporating waste plastic results in cost savings and reduces reliance on natural aggregates. Concrete cubes demonstrate maximum compressive strengths of 17.31 N/mm² (0% plastic waste), 18.32 N/mm² (15% plastic waste), and 17.48 N/mm² (20% plastic waste), indicating a diminishing strength trend with increased plastic content. Future research could focus on improving the bond between plastic and cement particles to enhance cohesion and expand the applicability of waste plastic-concrete mixtures.
