Early attainment of strength in rapid hardening cement is mainly due to finer grinding.

Its clearly written in books that the early strength of opc is due to fine grinding is responsible for its early strength. Also C3S is responsible for its early strength. So please, any body give the correct option.

Finer grinding and tricalcium aluminate C3A causes rapid hardening.
While early strength is given to the cement by tricalcium silicate C3S.

It’s due to fine grinding and also c3s.

All the options are participating in the high strength at early stage. To make RHC they are burnt at higher temperature and grinded fine.
Also increasing the lime content increases the amount of C3S. Hence all the options are correct. The answer is all of above.

It is due to the large proportion of lime grinded finer than the normal cement.
