PROBLEM TO BE SOLVED: To properly restrain corrosion of a steel material buried in concrete by electric anticorrosion.SOLUTION: A corrosion prevention system comprises a concrete structure 102 with a reinforcement 101 buried therein and a plurality of voltage impression parts 103a, 103b, 103c and 103d buried in the concrete structure 102 together with the reinforcement 101. The voltage impression parts 103a, 103b, 103c and 103d comprise respectively reference electrodes 104a, 104b, 104c and 104d and counter electrodes 105a, 105b, 105c and 105d. For each of the plurality of voltage impression parts, a control part 106 controls electric potential between the reinforcement 101 and the counter electrode, into a state where an electric potential difference between the reference electrode and the reinforcement 101 becomes electric potential of a stable area of Fe regulated by a Pourbaix diagram of the Fe. |
