Estimating Sulfate Effective Diffusion Coefficients of Stabilized Fluorogypsum for Aquatic Applications
Publication: Journal of Environmental Engineering
Volume 144, Issue 9
Abstract
The sulfate release from solidified/stabilized fluorogypsum was measured to develop the effective diffusion coefficients () as a parameter to assess the dissolution potential in aquatic applications. Specimens from 11 compositions consisting of 60–90% pH-adjusted fluorogypsum (pFG), 2–10% Type I/II portland cement (PC), and 0–38% Class C fly ash (FA) were exposed to solutions of (saltwater), (brackish water), and (freshwater) total dissolved solids (TDS). The effects of composition and salinity, measured as the TDS, on the sulfate were determined to select the compositions for use in various aquatic environments. The results indicated that the solidified/stabilized pFG had a lower dissolution potential in saltwater and freshwater in comparison with brackish water. On the basis of the low and low critical times (the time when the diffusion out of the specimen equals the precipitation onto the specimen), a composition of 80% pFG, 10% PC, and 10% FA is recommended as an alternative to limestone in saltwater and freshwater applications.
