WebbThe result of the slump test is a measurement of how concrete behaves when compressed into the shape of an inverted cone when subjected to the force of gravity. It does this by measuring the consistency of the concrete as well as its level of wetness, which then provides a notion of the mix’s condition in terms of its workability.
