Gypsum prevents the Flash Setting of cement during manufacturing. It retards the setting time of cement. Allows a longer working time for mixing, transporting, and placing. When water is mixed with cement aluminates and sulfates get to react and evolve some heat but gypsum acts as a coolant and brings down the heat of hydration.
Gypsum is added to cement clinker to: Assertion :Gypsum is added to powdered clinkers to get cement. Reason: Addition of gypsum to clinker decreases its setting time and thus cement hardens readily on mixing with water.
