Honeycombing in hardened concrete is most commonly associated with
Correct answer: D. Insufficient compaction of placed concrete
- A. Excessive hydration of cement
- B. Excessive fineness of cement
- C. Very low temperature during curing
- D. Insufficient compaction of placed concrete
Explanation
Insufficient vibration or compaction leaves voids between coarse aggregate particles and produces a rough, porous surface called honeycombing. Poor formwork joints and congested reinforcement can make the defect more likely.

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.
