A concrete mix with a high paste volume is generally more workable, but it is also more likely to experience
Correct answer: A. Drying shrinkage
- A. Drying shrinkage
- B. Aggregate crushing
- C. Flash setting
- D. Loss of cement hydration
Explanation
More paste can lubricate aggregate particles and improve workability, but the larger volume of cement paste can increase drying shrinkage. Aggregate crushing and flash setting are governed by different causes.

About Concrete Technology
Concrete technology covers cement, aggregates, water and admixtures, including their properties, proportioning and effect on fresh and hardened concrete. It explains workability, water-cement ratio, setting, hydration, strength, durability, curing, mix design and common defects, while distinguishing segregation and bleeding from general loss of workability.
