Slump tests are performed to empirically measure the workability of fresh concrete. It is used to measure the consistency of the concrete. In general, there are three different types of slumps that occur in slump tests.
They are as follows:
True Slump
Shear Slump
Collapse Slump

True Slump:
This type of slump is characterized by the general drop in the concrete mass evenly without visible signs of deterioration or disintegration. Shear Slump: It indicates that the concrete mix is deficient in cohesion. This type of slump leads to segregation and bleeding. Henceforth, in the long run, affecting the durability of the concrete.

Shear Slump:
It indicates that the concrete mix is deficient in cohesion. This type of slump leads to segregation and bleeding. Henceforth, in the long run, affecting the durability of the concrete. Collapse Slump: This type of slump is indicates that the mix of concrete is simply too wet. The mix is considered to be harsh and lean.
