  • Corrosion detecting probes for use with a corrosion-rate meter for electrochemically determining the corrosion rate of reinforced concrete structures
    Patent number: 5259944
    Abstract: A corrosion detecting probe is to be used in combination with an electrochemical corrosion-rate meter for performing on-site diagnosis of the corrosion rate of metallic reinforcement systems in concrete structures. After the probe is brought into surface contact with a concrete member, voltage/current signals are applied thereto and a series of calculations are performed to determine the polarization resistance directly about a confined concrete portion. The probe consists essentially of an external counterelectrode, a central counterelectrode, a central reference electrode and a pair of extra reference electrodes (sensors). A current applied from the external counterelectrode serves to repel the lines of current (resulting from a voltage signal first applied at the central counterelectrode) below the probe and within the confined concrete portion which is between the central counterelectrode and the external one.
