The initial setting time of cement indicates the time available for
Correct answer: C. Concrete mixing, placing and compacting
- A. Concrete to attain its design strength
- B. Concrete to complete long-term shrinkage
- C. Concrete mixing, placing and compacting
- D. Aggregate particles to reach saturated absorption
Explanation
Initial setting marks the beginning of loss of plasticity, so it indicates the practical period for mixing, placing and compaction. It does not represent the time required to achieve structural strength.

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.
