A concrete mix shows separation of coarse aggregate from the cement mortar during handling. This defect is called
Correct answer: B. Segregation
- A. Bleeding
- B. Segregation
- C. Plastic shrinkage
- D. False setting
Explanation
Segregation is the separation of the constituents of fresh concrete, commonly because of excessive handling, poor grading, or excessive water. Bleeding specifically refers to water rising to the surface.

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.
