Based on the results of the experimental investigation, following conclusions could be drawn as follows: In Concrete, Natural sand can be replaced with plastic waste by 10 to 20% to achieve green concrete. Sand can also be replaced up to 30% in the members of building which do not carry high load. Using plastic waste such as polyvinyl chloride (PVC), Polypropylene (PP), Polyethylene in concrete reduces the environmental issues and minimizes the difficulties of dumping the major plastic waste. This will help to tackle the increasing pollution all over the world, especially in countries that face the complications regarding waste. In addition to the environmental benefits, it was noted that using plastic scrap can be used to fight against the obstacle of scarcity of natural sand in India. Also it was perceived that using aluminum powder in concrete containing plastic waste will minimize the dead load of concrete which is of crucial importance. Ultimately the use of such plastic waste material cuts down the cost of construction and also the aftermath of using plastic scrap in concrete will be magnificent.
