Concrete incorporating steel fibers poses difficulty in mixing, transporting, placing and compacting that may lead to voids in hardened concrete. The determination of fresh fiber reinforced concrete properties is therefore, important for satisfactory performance in hardened state. The present experimental study investigates effect of three fiber properties-volume fraction of fiber, aspect ratio of fiber and diameter of fiber- on the rheological properties of high performance concrete with a parallel plate rheometer. The test result shows that yield stress and plastic viscosity are adversely affected by all the three parameters. Fiber volume concentration has the highest effect on the measured rheological parameters whereas fiber diameter has the least effect.
