In this study, we evaluate the chloride ion permeability of steel fiber rein-forced concrete. NT Build 492 experiment was used for the evalation. During the cast of SFRC, compaction works were done in same level. As a result, the chlorine ion permeability of the steel fiber rein-forced concrete is affected by Water-cement ratio. Effect of pores in the SFRC on permeability is dominant. In conclusion, it is important to get better quality of during cast in accordance with the addition of steel fiber ratio.
