Effect of Steel Fiber on Resistance of Ultra High Performance Fiber Reinforced Concrete Plates Under Impact Load
Ultra High Performance Concretes are significantly improving the bearing capacity of the structures under static as well as dynamic loads. An investigation on the behavior of Ultra High Performance Fiber Reinforced Concrete (UHPFRC) plates subjected to impact load was conducted in this study with three main factors of steel fiber, the strength of the concrete, and the amount of rebar. At the material level, a concrete grade of C120 and a steel fiber content of 1.0, 1.5, and 2.0% by volume respectively were used. All the samples have dimensions L500 mm x W500 mm x T80 mm, they are divided into two groups of with and without reinforcement. The experimental model is set up with a free-falling load acting at the center of the upper surface of the plate. Experimental results show that the steel fiber content directly affects the mechanical properties of UHPFRC such as compressive strength, flexural strength, fracture energy, and toughness of the material. The crack propagation corresponding to the impact loading is influenced by the amount of steel fiber in the concrete.
