Calcium Sulfoaluminate Cement – Royal White Cement

Calcium Sulfoaluminate (CSA) is a specialty cement used in many appliions where high early strength and fast setting development are necessary, such as bridge decks, airport runways, patching roadways, DOT work, tunneling, etc. CSA cements may also be used to manufacture shrinkage compensated or low shrinkage concretes grouts and mortars.
