Abstract: Since the invention of concrete in the early 18th century, there has been a constant rise in efforts to increase the productivity of this material so that it becomes more economical. The economy of concrete also depends on the use of products that are abundantly available in the near vicinity, at the least processing costs. One such material is the coal ash. It is an unavoidable residual yield of the thermal power plants which are the major electricity producers in India. The 120 power plants produce 120-150 million tons of fly ash per year. The disposal of this fly ash is a complicated task as it takes a very large space to dump, also this causes air pollution and harmful health conditions when inhaled. Many attempts have been made to utilize this material in the recent past. One such attempt is the use of fly ash in concrete. Is has been found that fly ash can be used as an important constituent of concrete in the form of aggregates. The market for fly ash aggregate has one of the most intriguing opportunity for business owners as use of fly ash has no seasonal problems, as it could be stored for a very long time in open surroundings without the risk of losses, environmental hazard or freeze-thaw condition complications. The use of fly ash aggregates is a very good application for the disposal of fly ash.
