The final setting of cement indicates that the cement paste has
Correct answer: A. Lost its plasticity and gained substantial rigidity
- A. Lost its plasticity and gained substantial rigidity
- B. Just begun to lose its fluidity
- C. Reached its maximum compressive strength
- D. Completed all hydration reactions
Explanation
Final setting marks the stage when the paste has lost plasticity and become sufficiently rigid. It does not mean that hydration is complete or that maximum strength has been reached.

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.
