Abstract—The durability of reinforced concrete structures in marine environment has been investigated as a serious problem in concrete construction technology where the chloride attack was an interested topic. Chloride attacking the reinforced concrete structure through the crack is complicate and more dangerous than uncracked concrete. In this paper, the chloride diffusion into cracked reinforced concrete was studied by a basic of migration tests. The crack is a cause for increasing chloride penetration depth, there the crack depth plays an important role. Besides crack depth, the crack width is also investigated to obtain its influence on the chloride penetration depth. Kind of crack investigated is natural crack (V-shape crack) and it is generated by bending moment of reinforced concrete beam.
