EMBEDDED-IN CONCRETE REINFORCING STEEL CORROSION ENVIRONMENT MEASUREMENT SENSOR ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide an electrode for an embedded-in concrete reinforcing steel corrosion environment sensor that makes it possible to more correctly measure a state of concrete of a detection object.SOLUTION: An electrode 10 for an embedded-in concrete reinforcing steel corrosion environment measurement sensor is composed of a cylindrical first conductive member 11 to be inserted into an electrode installation hole to be provided in a concrete structure body; and a second conductive member 12 to be inserted into a hollow part 14 of the first conductive member 11. The first conductive member 11 has an insulation part that comes into close contact with an inner wall of the electrode installation hole in an entire periphery in a bottom surface to be arranged on a bottom side of the electrode installation hole, in which a diameter is enlarged with the second conductive member 12 inserted thereinto and a side surface comes close contact with the inner wall of the electrode installation hole in the entire periphery. The second conductive member 12 has an insulation part that comes into close contact with the inner wall of the electrode installation hole in an entire periphery in a bottom surface to be arranged on an opening side of the electrode installation hole, has a connection line 22 with respect to a power source to be installed outside the electrode installation hole, and comes close contact with the first conductive member 11 in a state where electrification is possible when inserted into the hollow part 14.SELECTED DRAWING: Figure 1
