Abstract -The plastic waste is one of the most hazardous pollutant for environment because of slow degradation process, the plastic take a year to degrade. Plastic waste accumulation has become a major environmental issue worldwide. One innovative approach to addressing this challenge is its incorporation into concrete as a partial replacement for conventional materials. This study explores the feasibility of using plastic waste, such as polyethylene terephthalate (PET) bottles, polyvinyl chloride (PVC) pipes, or other types of plastic waste, in concrete mixtures to enhance sustainability. The idea behind this experiment is to overcome these plastic waste with the reuse as a constructional material in order to overcome the environmental problems that the world is facing. The research investigates the effects of replacing fine or coarse aggregates with plastic waste in varying proportions. Key properties, including workability, compressive strength, tensile strength, and durability, are analyzed. Results indicate that while excessive plastic content may reduce mechanical strength, an optimal percentage can improve impact resistance, reduce density, and offer an eco-friendly alternative to traditional concrete. This paper aim to review the usage of the plastic waste. It is added into the concrete in a range of 5% , 10% and 15%. After the casting and curing of concrete cubes, we are going to conduct destructive compression tests, non destructive compression tests, characteristic properties of concrete tests on modified concrete cubes and conventional concrete cubes of M25 grade concrete. As the result the experiment result is compared with modified concrete cubes to conventional concrete cubes the strength is decreased.
Key Words: Plastic waste, Environmental pollution, Sustainable construction, Concrete modification, Waste management, Recycling.
