EFFECT OF STEEL FIBER CORROSION ON MECHANICAL PROPERTIES OF STEEL FIBER REINFORCED CONCRETE

In developing countries, usage of steel fiber-reinforced cementitious composites is widely expanding in structures, due to their high mechanical performance and flexibility. In this paper, the behavior of steel fiber-reinforced concrete exposed to corrosive environments has been investigated. Three test programs were conducted: one dealt with the effect of corrosion on steel fiber-reinforced mortar specimens, next considered the effects of using pre-corroded fiber in mortar specimens, and the other dealt with the effect of corrosion on the behavior and the failure modes of a single fiber pull-out test. Different exposure periods, types of solutions and the temperature of environment were taken into account.
