Question

Slump and compaction factor are two different measure of workability of concrete. For a slump of 0 to 20, what is the equivalent range of compaction factor ?

• A. 0.4 - 0.7
• B. 0.7 - 0.9
• C. 0.7 - 0.8
• D. 0.6 - 0.8

Answer 1

The correct option is C 0.7 - 0.8

For slump value of 0 to 20, the compaction factor would be 0.78 and workability is categorized as very low.
