Graphical abstract

Concrete, being the construction material that is extensively employed, possesses various limitations despite its adaptability in building projects. It exhibits weakness when subjected to tension, has restricted ductility, and offers minimal resistance against cracking. Concrete is widely used in construction due to its high strength. The aim of this study is to conduct experimental research on the utilization of PET fibre as a construction material in concrete, which is technically sound and environmentally safe. The use of PET fibre in various engineering applications can solve the problem of disposal of plastic waste. PET fibre can be used in concrete to improve its ductile parameters. PET wires of 50 mm in length and 3 mm in width are used in this work. The tests conducted on M30 grade concrete included assessments of its strength in compression, strength in split tensile, strength in flexure, and resistance to impact. The percentages of addition were 0 %, 0.25 % and 0.5 % density of fibre. The impact properties of PET fibre concrete were studied. Test results showed that there is improvement in compressive strength, split tensile strength, flexural strength and a significant increase in impact resistance of concrete after the addition of PET fibres.
