The test has been typically used in precast operations and at large construction sites. Some of the work imparted into the concrete is lost in friction between the hoppers and the concrete. The magnitude of this friction varies between different concrete mixtures and may not reflect field conditions.The compaction factor test gives more information (about compactability) than the slump test,
