Abstract
Various examples are provided for corrosion detection in structural tendons. In one example, among others, a method includes injecting current through a portion of a tendon assembly including a tendon at least partially encased in grout, where the current is injected through the portion of the tendon assembly via contact points on a surface of the grout. A potential across the portion of the grout surface is measured and a condition of the tendon can be based at least in part upon the current and the potential. In another example, a system includes supply electrodes to inject current into grout surrounding a tendon via contact with a surface of the grout, sensor electrodes to measure a potential difference between the supply electrodes, and an impedance detection device to determine an impedance of the tendon based at least in part upon the injected current and the potential difference.
