Which cement is most suitable when a concrete structure requires reduced heat generation during hydration?
Correct answer: A. Low-heat Portland cement
- A. Low-heat Portland cement
- B. Rapid-hardening cement
- C. High-alumina cement
- D. Quick-setting cement
Explanation
Low-heat Portland cement is formulated to release heat more slowly and is useful in massive concrete where thermal cracking is a concern. Rapid-hardening and quick-setting cements are selected for faster strength or setting, not reduced heat.

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.
