Abstract
In its role of providing technology to promote the efficient use of minerals and mineral process waste, the U.S. Bureau of Mines conducted research at its Tuscaloosa (Alabama) Research Center to identify and develop high-volume uses for phosphogypsum. Mixtures containing a maximum of 5 pct phosphogypsum, 6 to 10 pct lime, and the remainder fly ash had compressive strengths as high as 4,800 psi. The effects of the amounts of phosphogypsum, lime, and fly ash were investigated. Also, the effects of fly ash to lime ratios were studied.
