Polyethylene Terephthalate is a synthetic material referred as PET. Strapping means process of bundling with the help of various straps and strapping tools. PET strap is a strong material used for packaging of various goods. PET strap has high resistivity against temperature and high tensile strength. It is commonly used in all industries for packaging and bundling. In this experimental work, an attempt has been made to use of PET strap in concrete in the form of fibres to study the behavior of compression members for the addition of different aspect ratio of PET strap fibres like 0, 33, 55, 77, 99, and 122. Totally 18 concrete cubes of size 150 x 150 x 150 mm were casted and cured for 28 days for the nominal mix proportion of 1: 1: 2 with a w/c ratio of 0.45. Series of tests were conducted, such as ultrasonic pulse velocity, rebound hammer, and compression test at laboratory. Based on the obtained and evaluated test results, it was concluded that aspect ratio of '55' is the good aspect ratio of PET strap fibres and it can be added upto 2% by weight of cement for the production of PET strap fibre reinforced concrete.
