    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 formation of concrete.
