Nowadays due to rapid industrialization and urbanization the world facing massive problems such as shortage of natural construction material and increase in the plastic waste. It is essential to manage both problems as early as possible. The purpose of this investigation is to examine the custom of waste plastic as a coarse aggregate in the concrete mix of M20 grade concrete in a fractional way.
In this investigation, the seven mixes are prepared by using plastic waste as a coarse aggregate. In the present study, the natural coarse aggregate is exchanged by plastic coarse aggregates’ in various percentages such as 0, 2, 3, 4, 5, 6, and 7%. Various concrete specimens are casted and tested by considering this percentage to find out the interpretation of recycled plastic as a replacement of coarse aggregate that would affect the development of strength in the concrete. It’s observed that up to 5% replacement of ordinary coarse aggregate by plastic coarse aggregate the compressive strength of concrete will increases, after 5% it starts decreasing. Also, the tensile strength of concrete increases up to 4% and after that it starts decreasing. The additional tests are conducted to check the density of concrete and it is was observed that an increase in the percentage of plastic will decrease the density of concrete.
