Manufacture of Portland Cement- Materials and Process
After the initial setting time of the cement, the cement becomes stiff and the gypsum retards the dissolution of tri-calcium aluminates by forming tricalcium sulfoaluminate which is insoluble and prevents too early further reactions of setting and hardening. 3CaO.Al 2 O 3 + xCaSO 4.7H 2 O = 3CaO.Al 2 O 3.xCaSO 4.7H 2 O. 4.
