Materials ground Portland clinker is the main constituent of most cements. In Portland cement, a little calcium sulfate (typically 310%) is added in order to retard the hydration of tricalcium aluminate. The calcium sulfate may consist of natural gypsum, anhydrite, or synthetic wastes such as fluegas desulfurization gypsum.

Highlights Comparing industrial clinker grinding for three different grinding systems. Energy consumption and cement quality variations at the same cement fineness. The HPRM cement was superior in strength development, particularly at early ages. The grinding systems produce cements with different temperatures. Temperature difference affects the degree of gypsum dehydration and cement quality.
