Repair materials that consist of an inorganic material such as cement mixed with rebar corrosion inhibiting material are widely used for the repair of salt-damaged RC structures. However, there are few examples of the use of organic materials such as epoxy resins, which are widely used as repair materials, as a countermeasure against salt damage. Making possible the use of epoxy resin as a repair material for salt damage would allow the implementation of salt damage countermeasures across a wide range of applications. This paper reports on the properties of salt adsorption type epoxy resin made by adding a salt-adsorbing agent to organic epoxy resin as a repair material, and examples of its appliwcation to reinforced concrete structures that have suffered salt damage.
