Q: Use of Finer cement particles leads to
  • A. d surface area for hydration
  • B. Inconsistent cement slurry
  • C. IncreaseLess cement strength
  • D. Reduced surface area for hydration
Correct Answer: Option A - Fineness of cement– It is the property of cement that given an idea about size of particle in cement and thus surface area. • Increase in fineness, increase in heat of hydration this is due to an increase in surface area of cement requires more water content. • Bleeding reduces by increasing the fineness of cement the due to an increase in surface are, adsorb content. • By the increase in fineness, surface increase thus, it requires more water, and if calculation not done properly, dry shrinkage possible to occurs in concrete structures.
