Repeatability, Responsiveness and Relative Cost Analysis of SCC Workability Test Methods


There are several workability test methods proposed to evaluate workability of self-consolidating concrete (SCC). Most of these methods are not standard, and their reliability is still under question. In this study, a comprehensive experimental program and statistical analysis were performed to evaluate the repeatability, responsiveness and relative cost of commonly used SCC workability test methods. Ten different tests including the slump flow, V-funnel, J-ring, L-box, U-box, column segregation, segregation probe, flow trough, sieve stability and surface bleeding tests were considered herein. For evaluating the suitability of these tests, each test was repeated several times on SCC mixtures with different workability levels. The obtained results show that the slump flow and the J-ring tests are well suited for evaluating the flowability, and the segregation probe, column segregation and surface bleeding tests are appropriate tests for assessing the stability of SCC. Furthermore, when SCC is planned for use in congestly reinforced members, it is recommended to use the U-box and the V-funnel tests in addition to the former ones to ensure the passing ability of SCC mixture and avoid any blockage.
