In this study, sodium chloride is directly mixed with binders in order to simulate harsh environments by promoting the corrosions of fibers and cement-based matrix including UHPC (Ultra High Performance Concrete). The experimental variables are the amount of sodium chloride and material composition such as UHPC, high strength mortar, and normal mortar. The experimental results show that UHPC has the superior capability to resist chloride ions due to its dense microstructures.
