1,Collapse Slump2,Shear Slump3,True Slump1,Collapse Slump In a collapse slump the concrete collapses completely. A collapse slump will generally mean that the mix is too wet or that it is a high workability mix, for which slump test is not appropriate.2,Shear Slump In a shear slump the top portion of the concrete shears off and slips sideways. OR If one-half of the cone slides down an inclined plane, the slump is said to be a shear slump. If a shear or collapse slump is achieved, a fresh sample should be taken and the test is repeated. If the shear slump persists, as may the case with harsh mixes, this is an indication of lack of cohesion of the mix.3,True Slump In a true slump the concrete simply subsides, keeping more or less to shape This is the only slump which is used in various tests. Mixes of stiff consistence have a Zero slump, so that in the rather dry range no variation can be detected between mixes of different workiability. However , in a lean mix with a tendency to harshness, a true slump can easily change to the shear slump type or even to collapse, and widely different values of slump can be obtained in different samples from the same mix; thus, the slump test is unreliable for lean mixes.
