What is compacting factor of concrete?

The compacting factor of concrete is a measure of its workability, indicating the ease with which concrete can be mixed, placed, and finished. It is determined by comparing the weight of a partially compacted concrete sample to the weight of the same volume of fully compacted concrete. A higher compacting factor suggests better workability, while a lower factor indicates that the concrete may be too dry or difficult to work with. This test is particularly useful for assessing the suitability of concrete mixes for various construction applications.
