Formation of soluble anhydrite by salicylic acid extraction of calcium silicosulfate
AbstractCalcium siliconsulfate and anhydrite were subjected to extraction by salicylic acid in methanol. Only calcium silicosulfate was affected, leaving a residue which was identified as “soluble anhydrite.” The fraction of residue produced was close to that expected for stoichiometric precipitation of sulfate as CaSO4. It is suggested that soluble anhydrite found in cement clinker residues after salicylic acid extraction may form in a similar manner from sulfate ions dissolved in belite or alite.
