Test Materials
Coal slag.
"Black BeautyŽ" coal slag was purchased from Reed Minerals (Highland, IN). The manufacturer reports that in a typical analysis, the most abundant compounds are silicon dioxide, aluminum oxide, ferric oxide, calcium oxide, potassium oxide, magnesium oxide, and titanium dioxide, which respectively account for 47.2%, 21.39%, 19.23%, 6.80%, 1.60%, 1.47%, and 1.01% of the material (Reed Minerals, 1992). The typical free-silica content is stated to be less than 0.1% (Reed Minerals, 1992).
