Abstract

This paper proposes a novel approach incorporating Polyethylene Terephthalate (PET) with enhanced surfaces as a fine aggregate replacement in concrete production. The PET surfaces were enhanced by being covered with cement or Silica Fume (SF) and kept inside a microwave for a specific time period. Concrete mechanical properties were examined, with its fine aggregate being replaced by PET in volume ratios of 10%, 15%, and 20%. The results demonstrated that the proposed approach significantly improved concrete properties, with an enhancement in compressive strength and a decline in water absorption having been observed. This research provides a promising roadmap for effective, sustainable construction practices.
