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.

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

It is option D.

Higher content of tricalcium silicate.

In RHC cement=finner grinding & high% of C3S &low% of C2S.

C3s, Only contribute hydration. Increased lime content helps to increase rapid hardening property.

Option A is correct.

Yeah, It is due to finer grinding.

Only option D is the right answer. Ref: R.S.Shetty.

Early stage strength of cement is responsible for "finer grinding & higher content of tricalcium " are correct.
