Recycled plastic aggregate used in the various proportion in the concrete mix and check their suitability. This study investigates the effects of using plastic waste as an alternative of Fine Aggregate. Disposal of plastic waste in an environment is considered to be a big problem due to the rapid growth of population in countries like India the disposing of solid waste is a major problem in our daily life. Solid waste management is one of the major environmental concerns. Among the waste material, plastic is the material that is the major concern to most of the environmental effects. There are different types of plastic which are classified on the basis of the physical property. As the plastic waste is non-degradable, it must be recycled or reused. The objective of the study is to study the behavior of the concrete which is made of the recycled plastic materials along with the study of the some of the physical properties that are related. In this study, M40 cement concrete is considered in which the recycled plastic waste is used as the replacement of fine aggregate in the concrete. Concrete cubes were cast taking 10 %, 20 %, 30 %, 40% & 50% of plastic as partial replacement of fine aggregate and tested for 7 & 28 days of compressive strength of concrete.
