Having a higher percentage of C 3 A, cement sets quickly, and releases a high heat of hydration. C 3 S gives the cement its initial strength, and makes it harden rapidly. On the other hand, C 4 AF has little to do with strength, but imparts the gray color to ordinary Portland cement. 'Heat of hydration' is the term used to describe the heat released when cement reacts with water during the ...

The first compound, C3S, reacts as soon as water comes into contact with cement, and continues reacting (hydrating) for the first 3 days or so. About 7 days after the cement has been hydrated, the C2S starts to react and continues for many months thereafter. When the cement is 28 days old, about 95% of the hydration has taken place.
