Experimental research on the behaviour of concrete containing waste plastic granules as a fine aggregate replacement

Abstract

With the tremendous increase in population and changing lifestyle of people, plastic has inevitably become a part of human life. In India about 5.6 million tonnes is generated as plastic waste per annum which leads to 15,342 TPD (tonnes per day). About 70% of plastic consumed is discarded as waste. Plastics have already started showing its alarming signs such as land pollution, ocean pollution, release of poisonous gases, soil infertility, immune disorder in birds etc. A prospective appeal to this is usage of plastic granules which are produced from low density polyethylene and high density polyethylene in concrete as a replacement of fine aggregate. The aim of this research is to compare the strength characteristics of conventional concrete of grade M20 with the plastic concrete. A potential application of plastic concrete is pavement base, sub base and lightweight concrete construction.
