&lt;p&gt;ABSTRACT Plastic waste is one type of solid waste that negatively affects the environment. A large deposition of plastic waste has resulted due to rapid urbanization. Industrialization also has a great influence on plastic waste increment. In the recent years, it was observed overstocked large quantities of waste plastic all over the world and the disposal from it require effort and cost in addition to the environmental pollution by poisonous gases including dioxins as a result of burning various types of plastic. It has become a source of threat to the environment of modern civilization because of the plastic materials are non biodegradable and containing toxic compounds, especially lead and cadmium, that mixes with the rainwater and pollutes the rivers, seas, oceans and the soil in the case of burial it, also, it needs hundreds of years to return to the cycle of nature. The plastics generation is growing exponentially every year, Especially the type of plastic called poly-ethylene terephthalate that are used for plastic bottle is mostly generated in high rate. The annual consumption of plastic drink bottles was estimated about 10 million tons, according to statistics of 2007, that is equivalent to 250 billion bottles and grows up to 15% every year. Some types of plastic can be used for many times without any health risks, but the polyethylene terephthalate (PET) is thrown to dust bin after using for once. This will contribute in aggravation of the environmental problems of the accumulation of the solid waste. The best solution to this problem is recycling the waste plastic by using it with other materials to produce materials having properties better than the original condition such as the concrete. This study has explained the effects of utilizing poly-ethylene terephthalate (PET) waste as a partial substitution of the fine aggregate(sand) in Carbon Fiber Reinforced Polymer laminated (CFRPL) concrete beam. It has been attempted to apply the concept of sustainability and reduce the environmental pollution by shredding the plastic bottles (PET) as small granular structure, partially replaced to the sand in ordinary concrete to improve the shear and flexural strength of reinforced concrete beams. The effect of poly-ethylene terephthalate (as sand replacement materials) and Carbon Fiber Reinforced Polymer sheet (which is laminated at tension part of the beam) on the structural behaviour of concrete beam has been analyzed independently as well as simultaneously through ABAQUS software. The structural behaviors like failure mode with crack propagation, shear strength, ductility and stiffness of concrete beam has been analyzed by using ABAQUS. The cross section of beam (200 X 100 X 2100) mm has performed by using ABAQUS for testing structural behavior. In present research structural behaviors of concrete beam has examined by replacing sand partially with PET plastic waste up to 50% and laminated with Carbon Fiber Reinforced Polymer (CFRP) through ABAQUS software. The fiber reinforced polymer laminated concrete beam containing PET has developed by replacing the natural fine aggregate with PET with substitution level of 0% ,10%, 20%, 30%, 40% and 50%. In the present study various structural behavior such as deflection, ductility, crack propagation and shear strength has determined for both traditional concrete and fiber reinforced polymer laminated concrete with sand replacement by PET fiber. The influence of plastic waste and carbon fiber laminated has observed on structural behavior of concrete and replacement of sand has optimized. It had been found that as the percentage of sand replacement with PET waste had been increased, the flexural strength gradually decreased. Due to the presence of carbon fiber reinforced polymer, the mid deflection and the ultimate failure load of the beam with carbon sheet had been increased. A large amount of deflection had been noticed from the combined effect of laminated CFRP sheet and replacement of sand with PET beams as compared to control beam. Beam which has laminated with CFRP sheet along with replacement of sand with PET up to 20% had shown better ductility than the vi control beam and also vertical crack had developed at the middle of the beams. The stiffness of the control beam was found as 0.77 kN/mm. But, the reinforced concrete beams in which the sand was partially replaced with PET up to 20% had relative lower stiffness compared to the control beam. A mathematical correlation has also developed in between various structural properties of concrete.
