ABSTRACT:
Significant growth in the consumption of plastic products is observed all over the world in recent years; this has contributed to increasing the production of plastic waste. Disposal of plastic is a challenging task. Because plastic waste can take anywhere from 20 to 500 years to decompose, and eventhen, it never fully disappears; it just get smaller and smaller. Hence it is necessary to reduce the amount of production of plastic as well as disposal and reuse of plastic is mandatory.
As decomposition of plastic is a serious problem as it takes very long time and adversely affection the environment in many ways so reuse of plastic waste in the production of concrete or mortar appears as an environmentally friendly solution for getting rid of plastic waste, due to its ecological and economic advantages and we can use it in construction, where we need life of structure to be improved. Furthermore, it leads to a decrease in plastic waste in landfills. Several studies presented the properties of cementitious composites (mortar and concrete) containing different types of (PWD)
Usage of these plastic waste materials helping in dual role by minimizing of concrete and by using the waste materials that are affecting the environment. The other advantage of using these waste materials is that they are helping improving the properties of concrete.This study summarizes the previous studies until 2019, discussing the use of recycled plastic aggregate as aggregates in cementation composites and its impact on the compressive strength.
In this study we are going to replace the fine aggregate and coarse aggregate by plastic aggregate with 2.5%, 10% and 25%, then specimens are tested and compared with a control specimen of 0% plastic in terms of compressive strength. We will also do the comparative study of replacement of fine and coarse aggregateand going to find that which replacement is better.
