Calcium Sulfoaluminate (CSA) is a specialty cement used in many applications 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.

High Early Strength / Rapid Setting: The primary advantage of CSA cements is that concretes, grouts and mortars made with CSA Cement, can easily be formulated to achieve compressive strengths in excess of 5000 psi in just a few hours. With CSA Cement is possible to attain desired 28 day strength in 24 hours. Rapid setting and high early strength gain is critical in situations where an airport runway, a bridge repair or a damaged freeway must be returned to service in a very short amount of time.
