Abstract

The study aims to investigate and test the behavior of steel fiber reinforcement concrete material at different dosage of fibers in concrete bridge decks. Concrete is a brittle material therefore the tensile resistance of concrete is low. Steel fiber reinforcement concrete material is a developed material that has been proposed to improve the tensile behavior of the concrete. Steel Fiber Reinforcement is popular material that is being studied to improve the structural behavior of reinforced concrete under different load conditions. Steel fiber-reinforced concrete (SFRC) provides improved tensile performance of concrete. This improved performance can be used in slabs to reduce the volume of conventional steel reinforcement, create longer spans, or reduce slab thickness. The project consisted of twelve concrete slabs has dimensions of (45 inches x 20 inches x 3.5 inches), twelve cylinders has dimensions of (6 inches diameter x 12 inches height) for split tensile test, twelve cylinders has dimensions of (4 inches diameter x 8 inches height) for compression test and twelve beams has dimensions of (6 inches x 6 inches x 20 inches) for modulus of rupture test. each three concrete slabs and specimens has same dosage of steel fiber reinforcement starting with 0.0%, 0.5%, 1.0% and 1.5% in order to investigate and exam the concrete behavior. The experiment revealed that the increase in the dosage of steel fiber fraction increases the compressive strength of the concrete in addition to that the breakout strength of concrete in tension increased. It is also found that the steel fiber improves the ductility of concrete and that is clear in the “Load- Deflection response figures” the area under the curves increases compare with normal concrete while the crack width became thinner with the increasing of the steel fiber dosage and preventing the sudden collapse as in normal concrete. Taking those results into consideration this can make a reduction in structural weight and improve the safety and speed up the construction and cost saving in the short term and the long term.
