Abstract:Because of increasing annual production volumes of fly ash, large volume applications, such as aggregate production, are beneficial in solving the disposal problem of fly ash while making economical use of a mineral resource. Aggregates have been produced from high calcium fly ash of Soma Thermal Power Plant and their engineering properties measured. For high volume utilization of fly ash, aggregate production involving pelletization and pressing into specially designed molds has been carried out successfully. Mechanical property and durability tests were conducted on the cured lightweight fly ash aggregates; five percent by weight lime addition to fly ash showed the best performance. It was also shown that different shapes of aggregates can be produced using the pressing technique.
