C3S = initial strength of concrete in 28 days.
C2S= final strength of concrete that is the ultimate strength.
C3A = initial setting time of concrete.
C4AF= a final setting time of concrete.
C2S= final strength of concrete that is the ultimate strength.
C3A = initial setting time of concrete.

C4AF gives colour to cement.
C3S has less resistance to sulphate attack and is responsible for initial strength.
- High heat of hydration.
C2S more resistance to sulphate attack and is responsible for ultimate strength (28days).
C3A responsible for the initial setting of cement. Very high heat of hydration.
