Abstract
Ultra High Performance Concrete (UHPC) is a new class of concrete that has gained a strong interest in research and application in the early 1990s, with outstanding properties such as a compressive strength in excess of 150 MPa and excellent durability. However, UHPC without any steel fiber exhibits low flexural strength and low crack resistance, even compared to that of high performance concrete, and the incorporation of steel fiber can compensate this disadvantages by bridging the crack at very small crack openings, transferring stresses and developing post crack strength in the concrete. This paper presents the effect of using steel fibers in enhancing the flexural strength and limiting of the crack-mouth opening displacement. The experimental results show that the incorporation of 3% steel fiber increases significantly flexural strength, up to 135%, and greatly limited the cracking due to the shrinkage, up to 8 times longer in comparable with those of the control sample.
