Selection and Use of Fly Ash for Highway Concrete (Final Report of Phase 1)
A suite of representative Indiana fly ashes was selected and sampled from power stations in all parts of the state, and tested to provide background information for selection and use of fly ash in highway concrete. Tests included complete chemical analyses and determination of soluble alkalies and sulfate; particle size distribution; surface area and specific gravity measurements; determination of content of magnetic (non-reactive) particles; x-ray diffraction; scanning electron microscope study; and determinations of pozzolanic activity index. It was found that most Indiana fly ashes were Class F materials, only two Class C fly ashes being among those sampled. Many of the Class F fly ashes were almost identical in chemical analysis parameters, apparently due to their common origin in local Illinois Basin coals. There were major differences among the fly ashes in carbon contents, particle size distributions, and other properties of importance with respect to prospective use of fly ash in highway concrete.
