Concrete subjected to a sustained compressive load generally undergoes a gradual additional strain known as
Correct answer: A. Creep
- A. Creep
- B. Elastic rebound
- C. Bleeding
- D. Segregation
Explanation
Creep is the time-dependent deformation that develops under sustained stress. Elastic rebound occurs after unloading, while bleeding and segregation are defects or movements in fresh concrete.

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.
