Which method is most suitable for measuring the workability of a very stiff concrete mix that has little or no slump?
Correct answer: A. Compaction factor test
- A. Compaction factor test
- B. Le Chatelier test
- C. Vicat soundness test
- D. Los Angeles abrasion test
Explanation
The compaction factor test is useful for low-workability concrete where the slump test may show little discrimination. The Vicat test concerns cement setting, Le Chatelier concerns soundness, and Los Angeles testing concerns aggregate abrasion.

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.
