The paper describes a study carried out to explore the potential for recovery of fly ash from wetstorage areas for use as an addition in concrete, and involved drying and processing material to achieve finer fractions/reduce particle size. Three relatively coarse fly ashes with medium/high carbon contents (lossonignition; LOI) were obtained from two UK lagoons and a stockpile.
