depending on the tricalcium aluminate and gypsum content of ordinary portland cement, the maximum ettringite content of the hydrated product at early ages is approximately 15%; cementing systems containing industrial by-products, such as fly ash, with lime and gypsum may have a higher ettringite content of, for instance, 20% (solem and mccarthy, …
PRODUCTION OF PORTLAND CEMENT Production of Portland cement is a complex technological process that consists of two basic steps. In the first, through heat processing entering raw materials are fundamentally altered creating cement clinker. In the second, by grinding and milling clinker wit gypsum the final product – cement – is manufactured.

A cement grinding plant, more commonly referred to as a clinker grinding unit or finish grinding plant, is an individual grinding plant in the finished cement production. Integrated cement manufacturing plants perform both steps, whereas cement grinding plants can grind clinker along with desired additives to make cement elsewhere.
Limestone-gypsum flue gas desulfurization process is the world's most widely used FGD technology. About 90% of Japan, Germany, and the U.S. power plants use gypsum desulfurization process, which is wet scrubbing using a slurry of alkaline sorbent, usually limestone or lime. Joyal has been engaged in limestone grinding for more than 30 years.
