This work evaluates the performance of concrete incorporating plastic waste as a partial replacement for fine aggregate, at replacement levels of 0%, 5%, 10%, 15%, and 20%. Various tests were conducted on fresh and hardened concrete to assess workability, strength, and durability. The slump cone and compaction factor tests were used to measure workability, yielding a slump range between 25–30 mm and a compaction factor of 0.98, indicating medium workability. Compressive strength tests revealed that concrete with 5% plastic replacement achieved near-optimal strength, comparable to conventional concrete, with a 28-day compressive strength of 30.01 N/mm². Similarly, the highest split tensile and flexural strengths were observed at 5% plastic replacement, beyond which strength values decreased as plastic content increased. The findings indicate that plastic waste can enhance certain mechanical properties when used at low replacement levels, particularly 5%, and offer a sustainable approach to utilizing plastic waste in concrete. This study underscores the potential of plastic-enhanced concrete as a viable alternative in construction, contributing to sustainable waste management practices.
