Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: The higher percentage of tricalcium silicate in cement results in rapid hardening with an early gain in strength at higher heat of hydration.
Reason R: A higher percentage of dicalcium silicate in cement results in slow hardening and less heat and hydration and greater resistance to chemical attack.
In the light of the above statements, choose the most appropriate answer from the options given below
