Compensation procedure for half-cell potential measurement

摘要

Non-destructive evaluation for corrosion of reinforcement is performed limitedly by the half-cell potential measurement. To compensate the measured potentials for reasonable corrosion estimation, theory of the half-cell potential is clarified and a modified boundary element method (BEM) analysis was developed. An applicability of the proposed procedure was examined by electrolytic tests of reinforced concrete slabs. By the modified BEM, the potentials at rebars were computed from the potentials measured at the concrete surface.
