This article presents an experimental investigation of PolyEthylene Terephthalate (PET) fibrereinforced concrete. Fiber-reinforced concrete reflects the upcoming trend to apply crack-resistant concrete more effectively. For example, PolyEthylene Terephthalate (PET) is a polyester polymer obtained from recyclable bottles; it has been widely used in the production of fibers for obtaining products based on the cement with improved properties. Therefore, fibers with lengths of 10 mm, 15 mm and 20 mm and fractions of volume of 0.05%, 0.18% and 0.30% equivalent to the concrete volume were used. Physical and mechanical concrete description to measure the workability of concrete was conducted. With the inclusion of PET fibers the concrete, it is observed that the workability remains almost same, hence there must be same effect on other mechanical properties of concrete but at the same time there will be lot of use of waste material like PET bottles. In this research, recycled PET fibers has been considered as reinforcement for concrete as means for studying and analyzing thereby improving its performance. Also the environmental benefit of successfully by means of a waste material give added benefit and had been a prime motivation for the work.
