Abstract
Plastic waste is increasing exponentially in these unprecedented times induced by pandemic outbreak of COVID-19. Therefore, in this study, efforts were made to assess the usage of plastic waste, in the form of polyethylene terephthalate fibers (PET-Fs), in concrete. Further, to enhance the properties of concrete, the PET-Fs were coated with sugarcane bagasse ash (SBA), which is another industrial bi-product. The PET-Fs were used in different proportion i.e., 3%, 6%, 9% and 12%, and of different aspect ratios (ARs) i.e., 25, 50 and 75, in the concrete specimens. The concrete specimens prepared in this way, were tested for different properties viz., compressive strength (CS), split tensile strength (STS), flexural strength (FS), workability (W) and density (D). It was observed that incorporation of PET-Fs in the concrete reduces these properties of concrete however, concrete with coated PET-Fs were having better properties than the concrete with uncoated PET-Fs. Therefore, it could be implied that coating of PET-Fs may enhance the applicability of PET-Fs as a construction material.
