Q. Is the slump test of value as a measure of consistency or workability? A. Yes, the slump test can be useful as an indication of consistency and, for certain mixtures, can also indicate workability. It does not, however, measure either characteristic separately or directly. Rheometers are being used to measure the basic flow properties of freshly mixed concretes (238.1R). References: SP-1(02); ACI 238.1R-08 Topics in Concrete: Concrete Fundamentals; Testing of Concrete
