Concrete behaves as a brittle material with low tensile strain capacity. By adding fibers, the cracking in concrete matrix is controlled, and the durability is improved. In this study, the microstructure and Chloride diffusion resistance of fiber reinforced concrete are compared with fiber type and fiber volume fraction. From the results, the fiber mixed in concrete must be at least 0.5% regardless fiber type, in order to ensure the chloride diffusion coefficient higher than OPC at 91days. However, the micro structure distribution is affected with fiber volume fraction and fiber type at range 10~100nm.
