The chemical water demand (CWD) necessary for complete hydration of belite-calcium sulfoaluminate-ferrite clinkers is calculated, taking into account gypsum added during final grinding. A series of equations are developed to predict CWD. These require a bulk chemical analysis of the clinker, which ...
