English Abstract

The concrete industry needs millions of tons of aggregate, comprising natural sands and gravel, each year. A similar notion can be stated in case of plastic as majority of the contemporary products and equipment in our daily life are made using plastic. Another resemblance of these two materials is their non-biodegradable character, and this raises plenty of questions to scientists and environmentalists. The utilization of recycled plastic during the preparation of concrete, as a partial replacement of natural aggregates, resolves the issues of safe disposal of waste plastic, reduces landfill anxiety over environmental protection and conserves our natural resources for the future. The aim of the proposed research was to assess the possibility of utilizing recycled waste plastic, as a partial/full replacement of natural aggregates. The concrete specimens prepared utilizing recycled plastics were tested to evaluate their mechanical properties and durability properties. From the experimental data, it is concluded that the mechanical properties decreased with the increase in the plastic content, the poor bond between the plastic and the cement paste is the reason for poor mechanical properties of the concrete. The durability of the concrete was marginally affected due to the incorporation of plastic aggregates. Due to the low unit weight and thermal conductivity values of recycled plastic aggregate concrete, there is a potential of using this concrete in construction applications.
