Higher content of tricalcium silicate.

It is option D.

The heat of hydration increased by c3s content increased so early strength develop and if fineness of cement increases with an increase in strength.

Option D is correct. Because early strength (i.e) the first 7 days strength depends upon tricalcium silicate. But we have the only option to increase the calcium content by increase the lime cement.

Burning at high temperature and fine grinding gives more strength of cement.

All the difference of rapid hardening cement to that of ordinary portland cement is the quantity of lime stone (tri-calcium silicate) used as raw material, which gives the high early strength to the cement.

I think the right answer will be D.

1st option along with 2nd option gives high strength at an early stage.
In Option D it is given tricalcium only. Not C3S.
Thus Option C is the correct answer.

Rapid Hardening Cement (RHC) are also called high early strength cement. The prime difference between the rapid hardening cement and ordinary Portland cement is the lime content. A large proportion of lime is the distinguishing feature of rapid hardening cement.

Can anyone explain, why we have a higher level of strength requirements for PCC compared to OPC at an early age (3 days and 7 days)?
