In this study, the mechanical properties of concrete reinforced with hooked and crimped steel fibers available in Iran with different volume fractions (for crimped fibers: 0%, 0.5%, 1% & for hooked fibers: 0.3%, 0.5%, 1%, 1.5%, 2%) were investigated. For this purpose, firstly several trial concrete mixes with different aggregate grading was assessed to choose the proper mix for shotcreting on surfaces. Then different amount of steel fibers were added to achieve 8 fiber- reinforced concrete (FRC) mixes. For each mix of the FRC, rectangular beams for determining flexural modulus, cubic samples for finding compression strength and cylindrical specimens for achieving elastic modulus and compressive strength were prepared and cured and tested. Results demonstrate that mechanical properties of concrete improve with addition steel fibers and effect of steel fiber reinforcement is maximum in case of flexural modulus. In addition, adding almost 1-1.5% hooked steel fibers into the concrete give optimal mechanical properties of concrete.
