Question

Increase in fineness of cement

• A. reduces the rate of strength development and leads to higher shrinkage
• B. increases the rate of strength development and reduces the rate of deterioration
• C. decreases the rate of strength development and increases the bleeding of cement
• D. increases the rate of strength development and leads to higher shrinkage

Answer 1

The correct option is D increases the rate of strength development and leads to higher shrinkage

Increase in fineness of cement increases rate of strength development by expediting the hydration reactions and increases shrinkage by leading to stronger reaction with alkali reactive aggregate making it more prone to cracking.
