I. M. Loya 1 and A. M. Rawani 2 1 Research Scholar, Mechanical Engineering Department, NIT Raipur 2 Professor, Mechanical Engineering Department, NIT Raipur ABSTRACT Fly ash can be utilized as a resources material in numerous innovative applications. The study attempts to identify promising applications that can significantly contribute in maximizing the utilization of fly ash. Based on the synthesis of relevant literature the study identified promising applications and categorized them into two groups: (i) key application groups for sustaining the existing growth in utilization (ii) key application groups for further increasing the utilization of fly ash. The findings of the study are expected to assist in formulation of strategy for sustaining and improving fly ash utilization.

Huge quantity of fly ash generated at coal based thermal power plants if not managed appropriately pollutes air, water and soil. On the positive side, fly ash is also a useful resource material [1]. Many R&D Labs / institutions have developed technologies for gainful utilization of fly ash [2]. Continuous progress in research and development has enabled fly ash to be utilized in numerous innovative products. Various authors [3,4,5,6,7,8,9] have reviewed possible utilization of fly ash. Fly ash can be innovatively utilized as a resources material for concrete [3,5], cement [3,5,7], light weight aggregate/concrete [5,7], brick [3,5,6], tile [3,5] block [3,5,6], road construction [3,5,6,7], agriculture [3,5,7,8,9], floriculture [9], adsorbents for cleaning of flue gas [7], water and wastewater treatment [3,7], waste stabilization and treatment [6,8], for construction of ash dykes [3], construction of dams [3], recovery of valuable metals [4,8], reclamation [6,9], mine backfill [7], zeolites [6,8] blackboard chalks [6], ceramic filters [6], wood substitute [5], embankment [5], production of mullite [8], glass [8], composite materials [8], landfills [9], etc. Some of the above applications are successfully commercialized as a result a large quantity of fly ash is utilized every year. According to Central Electricity Authority (CEA) in financial year 2012-13 about 163.56 Million Tons (MT) of fly ash was generated, out of which about 100.37 MT was utilized [10]. Such high utilization is desired and is required to be sustained. As there are many innovative applications of fly ash there is
