The influence of fiber RC beams under flexure on the chloride-induced corrosion

Case Studies in Construction Materials, 2022
Corrosion of rebars is the main cause of the deterioration of reinforced concrete structures. In an aggressive marine environment, rebar corrosion occurs due to chloride ion penetration of the reinforced concrete (RC). This paper presents the findings of
