The compacting factor is the ratio between the weight of the partially compacted concrete and the weight of the fully compacted concrete.

Compacting Factor Apparatus is used to determine the compacting factor of concrete with low, medium and high workability.

This device designed to undertake a more precise and sensitive test procedure than the simple slump test. The apparatus consists of two conical hoppers mounted on a cylinder. Each hopper has a hinged flange with quick release mechanism and everything is mounted on a rigid steel stand.
