Slump test is a field test used for determining the workability of concrete. It gives a measure of the consistency of concrete

The 3 main types of Slump are True Slump, Collapse Slump, and Shear Slump.

For dry concrete samples, the Slump height generally ranges between 25 to 50 mm. In the case of wet concrete samples, the Slump height varies between 150 to 175 mm.

A Slump value over 150 mm is generally considered a high value

Workability is the ease with which concrete can be mixed, transported, placed and, compacted. It is the work required to do full compaction.
