Compressive Strength of Waste PET Bottle Based Fibre

PET (polyethylene terephthalate) bottles have progressively turned into a crucial and fundamental piece of an everyday person’s life. Thus the need emerges to course these waste plastic containers to their ideal use. To add to it, incorporation of waste PET bottles in concrete composites is a promising technique for developing sustainable composite materials which may be applied to the construction industry. Hence concrete with waste PET bottles proves not only as an effective plastic waste management technique, but also an approach towards economic, environment friendly and sustainable development of building materials in the future. In the research work, an experimental study has been carried out to analyze the possibility of using waste PET bottle fibres with 3 different aspect ratios of 10, 20, and 30, in concrete at different replacement dosages of 0.5%, 1%, and 1.5% of sand by weight, and compared against control mix with no replacements of sand.
