Properties of Concrete Containing Waste Plastic Aggregate

Abstract

In our modern life style environment, the usage of plastic materials is increased day by day. Production of plastics globally would result in generating plastic-based waste. In recent times, many researches have been carried out to utilize the waste plastic waste materials in the concrete mix to make eco-friendly. The present study investigates the properties of concrete when replacing natural coarse aggregates (NCA) by bio non-degradable plastic aggregate up to 30%. Furthermore, fine plastic powder has been used in fine aggregate (FA) as partial replacement. Mechanical properties such as compression test, tensile strength test and flexural strength test have been carried out and the experimental results are discussed in detail. When the plastic aggregate percentage replacement increases, strength has been decreased because of poor bonding observed between the plastic aggregate and concrete reduces the strength properties.
