A Statistical Review on the Current Scenario of Generation and Utilization of Fly-Ash in India

Abstract

In this paper we focused upon the nature of Indian fly-ash and its various utilizations. In the past decade, there has been tremendous increase in the generation of fly-ash since more than 70% of country’s demand for electricity is met by coal-based thermal power plants. At present scenario, around 160 million-tons of fly-ash is produced which is nearly twice over the last decade. The disposal of such huge quantity of ash is a serious issue. With detailed knowledge, it could be gainfully exploited in different sectors, thereby conserving soil and other resources by acting as their substitute material. Many governmental agencies have been made responsible for the comprehensive exploration of associated hazards and potential applications of fly-ash for its better and increased consumption. Fly-ash is used in numerous sectors with majority application in construction and related activities. Various mitigation measures have been discussed in this paper viz. brick making, roads & embankments construction, cement manufacturing and agricultural uses.
