Abstract:
Results are presented on recent studies undertaken in England, the state of Georgia, and Australia, on the durability of a variety of concrete structures containing fly ash. Five of these structures have been in service for over 15 years, and some provided comparisons between fly ash concrete and plain concrete. Details of the fly ashes used in the structures are supported by background data on fly ash availability and use in the areas concerned. Design, construction, and service details for the structures are presented along with findings of on-site inspections. Assessments were made of: fly ash hydration characteristics; depth of carbonation; functional efficiency; and visible deterioration. Links are ascribed between the determined values.
