Preventing rapid setting of cement.<\/p>\n<p>Gypsum is added to portland cement to control the setting time of the cement. It does this by reacting with the calcium aluminate trihydrate (C3A) in the cement to form ettringite, which is a gel that takes up space and slows down the setting process.<\/p>\n<p>A.
