Calcium sulfoaluminate cement-containing inorganic

Calcium sulfoaluminate cement includes cements containing a mixture of components, including, for example, anhydrous calcium sulfoaluminate, dicalcium silicate, and/or gypsum. Calcium sulfoaluminate cement reacts with water to form ettringite and thus contributes to the high early compressive strength of the inorganic polymers.
