One of the main environmental problems today is the disposal of the waste plastics. The plastic waste is increasing day by day. On other side the construction industry is facing problem due to the insufficient and unavailability of the construction materials. So we need to search new construction material as well as an efficient method to the disposal of plastic waste. To find the solution of above two problems, one of them can be used to solve other. Hence the plastic waste was mixed with cement concrete in various proportions in between 0%-10% and the M20 grade test specimen were cast to study the behavior of plastic mixed concrete. The present topic covers the study of compressive strength, flexural strength of concrete.
