Abstract:Increased use of fly ash from coal-burning electric utility power plants for the manufacture of both cement and concrete appears to be a virtual certainty over the next several years. Representatives from fly ash producers (electric utilities), fly ash marketing and supply companies, and fly ash users from the cement and ready-mixed concrete industries met at two meetings in early March. The first was a conference sponsored by the Electric Power Research Institute (EPRI) in Palo Alto, California, for about 30 invited paticipants from the U.S., Canada, and several other countries also interested in the increased use of fly ash to reduce the amount going to waste ponds and landfills. The other meeting was the Sixth International Ash Utilization Symposium, jointly sponsored by organizations including the National Ash Association, the Federal Highway Administration, the Environmental Protection Agency, and the Department of Energy. It was held in Reno, Nevada; over 400 attended. These meetings provided an opportunity for frank discussion of proposals for greater use in concrete, needs for adequate quality controls and characterization of fly ash properties, the effect of coal and power plant operation on fly ash properties and usability, and comprehensive listing of needed future research. Factors influencing the use of fly ash and an estimate of trends which will have an impact on the construction industry are briefly discussed.* .
