Concrete is one of the most durable materials and has been extensively used in marine environment. Wharves, harbor reinforced concrete structures, immersed and exposed in the aggressive marine environment, are easily deteriorated and corroded.

Therefore, in the paper, wharves of five major commerical harbors around the island were surveyed in order to find the main factors of structures deterioration and to establish the feasible techniques of monitoring the corrosion of the concrete reinforcement.

From the survey results shown, the main evidences of R.C. structures corrosive might be reinforcement cover insufficient, designing and constructing not under marine structures construction criteria. These defects cause the chloride and sulfide penetrate into concrete structures easily and reduce the R.C. structures durable.

Eventually, using the results of chloride penetration on R.C. structures as a guide for predicting the service life of existing structures or designing a new structure for a given life.
