Utilization of recycled aggregate, plastic, glass waste and coconut shells in concrete - A review

Abstract

It is evident that the exploitation of waste increases insignificantly every year worldwide and is not recycled as per the need of the environment. Recycling of waste consumes a lot of energy and also leads to environmental pollution. In recent years, managing the waste which is causing a lot of environmental issues is one of the critical problems faced by the world. This waste mainly includes constructional demolition waste, agricultural waste, glass and plastic waste. All these cause a problem to dispose of after they have been used once. In order to deal with such a situation, the application of such waste in concrete production has become a great means of managing them. These wastes can be utilized as a partial or complete replacement of certain ingredients of the concrete. The recycling of these waste materials in concreting not only helps in managing solid waste but also renders the occurrence of natural resources. This review paper will provide an understanding of the adoption of waste materials as a resource during concrete production.
