Study of Mechanical Properties of Concrete using Waste Pet Bottle Fibres for the Reinforcement

Now-a days research on usage of innovative material in concrete to develop it characteristic has been increased. The main problem of the today's world is waste disposal. So researchers have to find new ways to reuse of waste material. Plastics waste has become a problem because of its non-degradable property. In plastic wastes a larger portion is shared by a type of plastic known as PET (Polyethylene Terephthalate). These are largely obtained for drink and mineral water bottles. In the present study the use of PET bottle fibres obtained by just cutting the PET bottle without any separate recycling process in concrete matrix is report. The test results of different mechanical properties on concrete specimens like Compressive strength, Split tensile strength, Flexural strength, Young's modulus of concrete, stiffness, Ultimate load, maximum central deflection for different proportions of fibre are be reported. The specimens are reinforced with fibres made from waste Polyethylene Terephthalate (PET) bottles and added with superplasticizers. In this study the dosage of the fibre are 0.25%, 0.5%, 0.75% by weight of cement and the dosage of the superplasticizers 0.8% by weight of cement. The results are very interesting, especially regarding the interlocking between PET and concrete.
