Environmental pollution caused by polyethylene terephthalate (PET) is getting more and more critical these days. However, polyethylene terephthalate, also known as bottle fibre material, can be added to concrete as aggregate replacement material in order to reduce environmental pollution. Food and fruit containers can also be made from polyethylene terephthalate. Polyethylene terephthalate is also a hard and stiff material which is resistant to chemicals and water. It also has excellent thermal and electrical insulation. The objective of this research is to determine the performance of PET fibre concrete in undamaged and damage states. Then, the concrete samples were tested using the Ultrasonic Pulse Velocity (UPV) method. The UPV method is an effective non-destructive testing (NDT) method for ensuring quality control of concrete materials as it helps detect damages in structural components. The UPV method is conventionally used for the quality control of materials, mostly homogeneous materials such as welded and metal connections. The fibres were simply cut from PET plastic bottles. The length and width of recycled PET fibres were fixed at 25 mm and 5 mm respectively. The chosen percentages of fibre used were 0.5%, 1.0%, 1.5% and 2.0%. The specimens underwent the UPV test and the compressive strength test on day 7 and day 28. It was found that the concrete quality slightly decreased when the percentage of PET content increased. Finally, the optimum percentage suggested based on the results is 1% of PET fibre as it achieved the highest compressive strength and UPV compared to normal concrete.
