Chloride-induced reinforcement corrosion in reinforced concrete structures exposing marine environment is one of the most importance factors affecting the durability of structures. In this paper, the influence of interfacial void around reinforcement due to bleeding on chloride ingress in RC members with flexural cracks is investigated through experiment and numerical simulation. The influence of interfacial void and its interaction between flexural cracks on chloride ingress into concrete under various conditions are systematically investigated through numerical simulation.
