Now a day are facing environment protection problems. Many things which are invented for our luxurious life are responsible for polluting environment due to improper waste management technique. One of them is a plastic which has to be disposed or recycled properly to maintain the beauty of our nature. On the other hand, urbanization growth will increase rubbish especially non-renewable ones. Eco friendly architectural principles are being incorporated into more buildings every day in the world but they are still out of reach of many people due to lack of knowledge and awareness. In this study is to explore the possibility of recycling a plastic bottles waste material. To address this issue the fibers from used plastics were added in various percentages in the M25 grade concrete. An experimental work has been carried out on the specimen’s cubes which were casted in the laboratory and their behavior under the test was observed. The plastic fibers were added from 0.0% to 3.0%. The compressive strengths of concrete were determined after 28 days of curing period and compared with control concrete. Experiments done shows increase in compressive strength by 12%. Plastic bottle fibre additive can be adopted. The plastic bottle fibre reduces the quantity of industry fibers used in concrete and also plastic bottle fibre is proved to be more economical.
