Abstract: Steel fibre concrete is a composite material that is well known and appreciated for its post-cracking tensile strength. This post-cracking tensile strength must be determined experimentally. Therefore, different test methods have been developed. The most popular are the Rilem 3-point bending test, the Rilem uni-axial tension test, the 4-point bending test and the wedge splitting test. All these test methods have reported a large scatter on the results, which is especially a problem if characteristic values have to be determined. It was shown in previous research that this large scatter is due to a non-uniform fibre distribution.
One of the possible solutions to avoid the large scatter is to increase the cracked area. In this context S. Bernard has developed a bending test on round plates supported on 3 points. This paper investigates the use of this test as a possible standard test. The scatter of the results of the plate tests was much lower than for the Rilem 3-point bending test. At this time a lot of design recommendations are based on the Rilem 3-point bending test. For this reason, it would be interesting to establish a link between the round plate test and the Rilem 3-point bending test.
