A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope. Movement is characterized by sliding along a concave-upward or planar surface. Comments.
A slump test is a method used to determine the consistency of concrete. The consistency, or stiffness, indicates how much water has been used in the mix. The stiffness of the concrete mix should be matched to the requirements for the finished product quality.hear 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. 1  If a shear or collapse slump is achieved, a fresh sample should be taken and the test is repeated.
