If concrete is placed and cured at a substantially higher temperature, cement hydration generally
Correct answer: D. Proceeds more rapidly at early ages
- A. Stops completely
- B. Changes aggregate into cement
- C. Becomes independent of water
- D. Proceeds more rapidly at early ages
Explanation
Higher temperature generally accelerates hydration and early strength development. Excessively high curing temperatures, however, may adversely affect later-age strength and durability.

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.
