Rapid hardening cement has greater strength in early stage as compared to opc. This is due to the extra amount of lime. So C is correct.

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.

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

MARI said:   6 years ago
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.

Manisha Parajuli said:   6 years ago
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.
