Abstract:
Corrosion of steel in concrete is a major problem in different countries around the world. Sometimes, dueto the weakness and inadequacy of designs and the more critical conditions than the initial predictions, concretestructures are exposed to serious damages, including corrosion; so that the corrosion of reinforcement has becomeone of the main reasons for the deterioration of concrete structures around the world. If the problem is not controlledproperly, it can lead to detrimental effects on the costs of maintenance and repair of damaged sections. In general, inthis research, 5 reservoirs in the central region of Guilan province (Kapurchal, Pir Bazar, Fakhrabad, Gilva Dashtanand talem seshanbe) that were subjected to chloride ion and suffered from corrosion, were selected to be examinedand evaluated; also, the tests of determination of chloride ion profile and diffusion coefficient were performed foreach of the reservoirs. Finally, some methods of repair and rehabilitation of these structures were discussed.
