  • Designing Concrete Mixtures University of Memphis

    ACI Mix Design. A measure of the degree of consistency and extent of workability is the slump. In the slump test the plastic concrete specimen is formed into a conical metal mold as described in ASTM Standard C143. The mold is lifted, leaving the concrete to "slump," that is, to spread or drop in height.
