An Experimental Study On The Properties Of Pet Fibre Reinforced Concrete

ABSTRACT Utilization of waste material in concrete would be beneficial in order to find an alternative solution to reduce environmental pollution. One of the waste materials is polyethylene terephthalate (PET) which is a polyester material and is produced in large quantities. In this work fibres are simply cut from waste plastic bottles reducing, in this way, the manufacturing costs of recycled PET fibre concrete. In India approximately 40 million tons of solid waste is produced, annually. This is increasing at a rate of 1.5 to 2% every year. Plastics constitute 12.3% of total waste produced most of which is from discarded water bottles. One possible solution is using RPET as short fibres in concrete. It can provide greater crack control and ductility enhancement capacities for quasi-brittle concrete as well as mass consumption alternative, which is a very important issue in the merit of recycling waste materials. The aim of this work is to explore the possibility of a waste material to be used in concrete as fibre. The dimensions of PET fibres used are 30 mm long, 5mm width and 0.6mm thickness in the various percentages 0%, 2%, 4%, and 6% of fibre in total weight of concrete. In this study cubes, cylinders, beams specimens are proposed to be carried out and their compressive strength, split tensile strength, flexural strengths will be compared. Then optimum percentage of PET fibre is found out. Keywords: Experimental Study, Properties, Pet Fibre, Reinforced Concrete
