Higher compaction factor implies higher workability.
A mix with good workability compacts easily.

Extremely low - 0.65 to 0.68.
Very low - 0.75.
low - 0.83 to 0.85.
Medium - 0.90 to 0.92.
High - 0.95.

More compaction, means more dense material, otherwise (lower workability).
For a good workability, compaction factor must be between (0.7 - 0.95).
For a good workability, compaction factor must be between (0.7 - 0.95).

The more compaction means more denser concrete and as 1% of air voids reduce strength by 5%, more compaction provides lesser voids which provides good strength.

In fact partial compaction happens during pouring & when we use vibration or other method of compaction we will get full compaction.
And since the sample obtains 95% i.e. it has high work ability.

As it goes towards 1 its work ability increases.

As the ratio between partially compacted and fully compacted concrete increases, the work ability of concrete also increases upto the maximum.

What is meant by wf and wp?
Sushan bastola said:

wp = wt of partially compacted concrete and wf = wt of fully compacted concrete.

Agree @MD Saleem Ansari.
