    Abstract

    Data from two research projects were analyzed to evaluate the suitability of seven empirical workability test methods for self-consolidating concrete (SCC)—namely, the column segregation test, J-ring test, L-box test, penetration apparatus test, sieve stability test, slump flow test, and V-funnel test. The results of these empirical tests were compared to rheometer measurements. Test methods were evaluated based on (1) the extent to which each method independently indicated filling ability, passing ability, or segregation resistance and (2) the ease and simplicity with which each test method can be used on a routine basis in the laboratory or the field. The data set consisted of 286 SCC mixtures incorporating a range of materials, mixture proportions, and workability characteristics. It was determined that the slump flow test should be used for filling ability, the J-ring test for passing ability, and the column segregation test or sieve stability test for segregation resistance.
