Fly ash is a potentially important engineering raw material that has yet to be extensively utilized. Of the 48 million short tons of fly ash produced in 1993 from burning coal in power stations in the U.S., only 22% was utilized, with the major use occurring in cement and concrete products. Utilization of fly ash represents a potential for utilities to both reduce costs and increase revenues. A major barrier to fly ash use is its variable nature, both chemical and physical, due to differences in source coals, boiler design and stack removal processes. Recovery of useful products from fly ash can improve the economics of fly ash utilization and offset costs associated with disposal.
