Sustainability Performance of Concrete Footpath with Polyethylene Terephthalate (PET) Bottles as Filler Materials
Abstract
PET bottles are solid wastes that are generated by human endeavours and these bottles being non-biodegradable constitute nuisance to the environment as it takes years for it to decompose. This study therefore, evaluates the environmental sustainability and performance of concrete footpaths incorporating Polyethylene Terephthalate (PET) bottles as filler materials. The investigation focuses on the feasibility, strength, and durability of using sand-filled PET bottles within concrete mixes to enhance construction sustainability. A stretch of unpaved path was chosen for the study. Sand-filled PET bottles were arranged and securely tied to prevent movement during construction. Concrete with a mix ratio of 1:3:6 was then poured over the bottles. The concrete's workability, compressive strength, and flexural strength were tested according to BS EN standards. The concrete mix demonstrated a slump value of 51mm, indicating moderate workability suitable for construction applications. The compressive strength measured at 23.513 MPa confirms the mix is robust and suitable for the intended use, particularly in walkway construction. Additionally, the flexural strength was 10.536 MPa, suggesting good tensile properties that enhance durability and reduce brittleness. The results reveal that using PET bottles as fillers not only reinforces the concrete but also addresses significant waste management issues by recycling non-biodegradable plastic waste. The study concludes that PET bottle-reinforced concrete footpaths offer a viable and environmentally friendly alternative to traditional construction materials, providing benefits in terms of both performance and sustainability.
