Cement has 4 component.
1. C3S it is quickly hydrated and a short time in give strength.
2. C2s it is a set time long periods and alternative setting time.
3. C3af training Calcium Alumino-ferrite.

Cement has 4 compounds which are known as Bogue compound.
1. Tricalcium silicate: It gives early strength.
2. Dicalcium silicate: It gives ultimate strength.
It also decreases the heat of hydration.
3. Tricalcium Aluminate:it rapidly reacts with.
Water. It is also responsible for the initial setting. It has a high heat of hydration.
4: Tetracalcium Amino Ferrite: It produces less heat. If increase the content reduce the strength slightly.

Decreasing order of rate of hydration.
C4AF > C3A > C3S > C2S.
C4AF > C3A > C3S > C2S.

Option B is correct.
The Rate of hydration C4AF>C3A>C3S>C2S.
The Heat of hydration C3A>C3S>C4AF>C2S.
The Rate of hydration C4AF>C3A>C3S>C2S.
The Heat of hydration C3A>C3S>C4AF>C2S.
