Utilization of flue gas desulfurization gypsum for

Sep 10, 2017 After the desulfurization of flue gas from CSA cement industry itself and other industries, the collected FDG gypsum can be applied in later two steps during CSA manufacture. On the one hand, FGD gypsum is able to provide as input materials for the CSA cement.

Desulfurization gypsum uses and properties take it as

Use desulfurization gypsum as cement retarder. Desulfurization gypsum has few harmful components. When used as a cement retarder, it can basically replace natural gypsum. The prepared cement performance is not much different from that of prepared with natural gypsum, even the cement strength will be a certain increase.
