A method is described for the electrochemical protection of reinforcement in concrete in harsh environments, for instance in contact with, or in close proximity to, seawater. On concrete a composition comprising graphite dispersed in a curable mineralic binder in the form of water glass or anothe r water-soluble inorganic silicate, a dispersion agent, optionally together wi th conventional additives is applied. The application is performed by spraying or brushing. An impregnation is optionally performed, either concurrent with th e application of the composition or thereafter. If necessary a post treatment is performed. Further, the use of the composition for electrochemical protectio n of reinforcement in concrete in connection with, for instance, quay constructions, bridges, bridge piers and similar constructions is described.
