Concrete Slump Test Procedure, Applications Types of Slump

Feb 16, 2017  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. Slump is a measurement of concrete's workability, or fluidity. It's an indirect measurement of concrete
