Technical feasibility for use of FGD gypsum as an additive setting time retarder for Portland cement
Journal of Materials Research and Technology, 2018 Flue gas desulfurization (FGD) gypsum was evaluated as a setting time retarder to replace the natural gypsum in the production of Portland cement (CP II E-32). The results of physical-chemistry and morphological characterization of both products showed a
