Utilization of Solid Waste Particles as Aggregates in Concrete

Abstract

The river sand is one of the unavoidable ingredients in Civil Construction. The Construction activities are increasing day by day. This usage of river sand is increasing its scarcity and its price in all parts of the country. Reducing the consumption of river sand in construction is a major issue while considering the Economic view. It also helps to save the environment by reducing the harmful impact of sand mining. The Discarded vehicle tyres which are historically been disposed of into landfills constitute an important part of the solid waste. Tyre disposal to landfills is problematic, as waste rubber is not easily biodegradable. An emerging field for the reuse of scrap tyres is in the production of concrete, where rubber tyres can be used as a partial replacement to natural aggregates. This has the additional advantage of saving in natural resources. In this study, an attempt has been made to control the environmental pollution and to save the natural resources by using the discarded rubber tyres for partial replacement for coarse aggregates and Copper slag for the partial replacement for fine aggregates.
