Over fifty million tons of coal fly ash are produced each year by coal-burning utilities in this country. While potentially useful in large-volume construction applications, such as fill, backfill, and grout, most of this material is disposed of as a waste product. One prerequisite to improved fly ash marketability is increased knowledge of its properties when used as a construction material. Numerous laboratory and field tests were performed to provide this information for fly ash-aggregate-cement slurry mixes, comparing the fly ashes themselves, various mix designs and curing conditions, and end product physical properties. This report includes results of testing performed by four laboratories. Eight Class F and four Class C fly ashes were tested. Parameters that were varied include aggregate, cement and water contents, curing condition and time, specimen size and shape, freeze-thaw cycles, and saturation. Measured properties include consistency, unconfined compressive strength, density, permeability, dimensional stability and modulus of rupture. Conclusions are presented as to relationships between test variables and the measured fly ash slurry properties. 30 figs., 11 tabs.
