Abstract: One of the major hurdles facing producers and contractors desiring to use Self-Consolidating Concrete (SCC) is the establishment of standardized test methods. Aside from tests that measure the fluidity of SCC mixtures, there is a need for standardized tests that quantify various aspects of SCC stability. Passing ability is one such stability (dynamic) characteristic. Three basic passing ability tests, namely, the U-box, the L-box and the J-Ring have been studied and to some degree implemented in either Japan or Europe. A comparison of these three methods was conducted by running various concrete mixtures designed to provide various degrees of passing ability. This paper describes the testing program and provides guidance on the usefulness of each test. The variables affecting test values are discussed as are potential standardized modifications to the test apparatus. A consensus on the usefulness of these various testing procedures will allow the writing of more consistent specifications on the use of SCC.
