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.

SAGAR said:   6 years ago
Higher content of tricalcium silicate.

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

Hithesh said:   7 years ago
C3s, Only contribute hydration. Increased lime content helps to increase rapid hardening property.

Vishal said:   7 years ago
Option A is correct.

Viru kapoor said:   7 years ago
Yeah, It is due to finer grinding.

Mahalakshmi said:   7 years ago
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.
