    Without gypsum however the clinker of low alite and high tricalcium aluminate phase behaved as flash set and in this case the rate of hydration of tricalcium aluminate phase was as high as 30 in 3 minutes after the mixing with water. With the addition of gypsum this value was lowered to 20 and the clinker became normal set.
