Detection of Calcium Sulfates and Magnesium Oxide in Fly Ash by X-Ray Diffraction.
Abstract
A procedure was developed to detect rapidly by quantitative X-ray diffraction the presence and amount of magnesium oxide (periclase) or calcium sulfate (anhydrite) in fly ash. This procedure was found to be capable of detecting these constituents in amounts as low as 0.25 percent by weight. Samples of material collected at six power plants using each of three flue gas desulfurization processes were examined. They all were found to contain calcium sulfate and all but one contained calcium sulfite. The constituents could be undesirable in material being added to portland-cement concrete if present in significant amounts.
