Title Of Article :
Effective Steel Fiber Type Investigation on Ultra High Performance Fiber Reinforced Concrete Beams
Abstract :
This study investigates the effective steel fiber type on ultra high performance fiber reinforced concrete beams with respect to flexural behavior. Five 100x150x1500 mm reinforced concrete beams, one is non-fiber and the others include four different steel fiber types, were tested in flexure. The concrete used in this study had compressive strength over 120 MPa and included 1.5% steel fibers by volume. Two types of hooked macro steel fibers (F30 and F60_1), double hooked macro (F60_2) and straight micro (F6) steel fibers were investigated. Evaluation of the effective steel fiber type on the flexural behavior were performed in terms of displacement ductility, load bearing capacity and cracking behavior. From the results of the study, it is determined that the most effective steel fiber for load bearing capacity and cracking control is double hooked steel fiber (F60_2) and most effective fiber for displacement ductility is straight micro fiber (F6).
