Title: Tensile Behavior fo Steel Fiber Reinforced Concrete - Evaluation of a Test Methodology

Abstract:Uniaxial tension tests of fiber reinforced concrete have been performed for determining the influence of several geometric parameters on the experimentally-obtained behavior. Molded cylinders were used as well as cores and panels cut from companion prisms. All specimens were notched at mid-height and the average crack opening was used for controlling the tests. The results show that the influence of the notch depth and specimen length on the stress-crack opening response is negligible, within the range studied. Comparisons with the results of cores demonstrate significant differences in the fracture behavior due to the preferential orientation of the fibers produced during compaction. It is also shown that the panels do not exhibit a representative behavior, especially when thin specimens are considered.
