What are the causes of Shear slump?

Shear slump is primarily caused by the segregation of concrete components, particularly when the mix is too wet or has a high water-cement ratio. Factors such as insufficient mixing, the use of poorly graded aggregates, and the presence of excessive fines can also contribute to this issue. Additionally, shear slump can occur when the concrete is subjected to lateral forces, leading to a loss of stability in the mix. Proper mix design and handling techniques are essential to minimize the risk of shear slump.
