Polyethylene Terephthalate (PET, PETE or polyester) is commonly used for carbonated beverage and water bottles. This is an environmental issue as waste plastic bottles are difficult to biodegrade and involves processes either to recycle or reuse. Today the construction industry is in need of finding cost effective materials for increasing the strength of concrete structures. This project deals with the possibility of using the waste PET bottles as the partial replacement of aggregate in Portland cement. Concrete with 2%, 4% and 6% PET bottle fibres for fine aggregate were produced and compared against control mix with no replacement. Considerable researches and studies were carried out in some countries like USA and UK on this topic. However, there have been very limited studies in India on plastics in concrete. Hence an attempt on the utilization of waste Poly- ethylene Terephthalate (PET) bottle granules as fine aggregate is done and its mechanical behaviour is investigated in compression, split tensile, flexural testing machine and fresh concrete test is also investigated Keywords— PET bottle, plastic flakes, plastic fibres, compressive strength, % replacement. INTRODUCTION Concrete is the most widely used construction material due to its high compressive strength, long service life, and low cost etc. However, concrete has inbuilt disadvantages of low tensile strength and crack resistance also. The use of fibre reinforced concrete has increased in the last decade.PET is one of the most important and extensively used plastics in the world Waste is the one of the challenge to dispose and manage. It has one of the major environmental, economic and social issues. Therefore, the waste bottle which challenge out in disposal can be binded out in concrete and disposal method which cause hazard to human being can be completely reduced and hence my project cover percentage replacement of fibre as fine aggregate. Impact on environment due to plastic waste Among different waste fractions, plastic waste deserves special attention on account non-biodegradable property which is creating a lot of problems in the environment. 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. The PET bottles cannot be disposed of by dumping or burning, as they produce uncontrolled fire or contaminate the soil and vegetation. Considerable researches and studies were carried out in some countries like USA and UK on this topic. However, there have been very limited studies in India on plastics in concrete. Hence an attempt on the utilization of waste Poly- ethylene Terephthalate (PET) bottle granules as fine aggregate is done and its mechanical behaviour is investigated in compression, split tensile, flexural testing machine and fresh concrete test is also investigated OBJECTIVES OF THE PROPOSED PROJECT The main objectives of this research proposal are to evaluate the possibility of using granulated plastic waste materials. The following were also proposed.  As partial substitute for the fine aggregate (sand) in concrete composites  To study the properties of PET.  To study the effect of PET over the compressive strength of concrete  To compare the strength of PET mix concrete with conventional concrete.  To determine the percentage of plastic fibre determines the strength IMPORTANCE OF THE PRESENT PROJECT The problem of disposing and managing solid waste materials in all countries has become one of the major
