Impedance-Based Detection of Corrosion in Post-Tensioned Cables: Phase 2 Extension of Sensor Development, Summary.

摘要

In this project, University of Florida researchers used electrochemical impedance spectroscopy (EIS) to detect corrosion in steel post-tensioning cables. In this method, a sinusoidal current is applied to the concrete surface in a range of frequencies. Researchers sought to design a sensor which uses EIS to monitor the integrity of the steel and grout in a post-tensioned system.
