Rapid hardening cement is similar to ordinary portland cement but with higher tricalcium silicate (C3S) content and finer grinding. It gains strength more quickly than OPC, though the final strength is only slightly higher.

Yes, Rapid hardening cement contains 56% of C3S.

@Johari you are right.

Rapid hardening cement gains strength quickly so, it required more amount of C3A.

While C3A is required for quick setting cement.

Option B is the correct answer.

Rapid hardening contains more C3S,

Whereas Quick settling contains more C3A.

Rapid Hardening cement has a maximum percentage of C3S.

Rapid Hardening Cement is also called high early strength cement.
