Increase in Fineness of Cement

Answer: A. Increases the rate of hydration

Increase in fineness of cement increases the rate of hydration.

Solution

Fineness of cement determines the size or fineness of cement particles.

• Fineness of cement is responsible for rate of hydration, heat of hydration and rate of gain strength.
• Finer the cement faster the rate of hydration and it develops early strength. Hence, an increase in fineness of cement increases the rate of hydration.
