Anchor Corrosion Detection

Anchor corrosion is an electromechanically process that is fairly well understood. The elements and conditions that contribute to, and exacerbate corrosion are known to include soil resistivity, presence of leakage current, moisture, age, grounding, etc. Even though the process is well understood, it is not easy to predict or detect the formation of a corrosion cell. The most proven detection method has been to fully expose the steel shaft by removing the soil around the shaft to the depth of the concrete footing. To do this for all guy anchors would be prohibitively expensive, so an accurate, non-invasive method to test in-service guy anchors would be useful. The ultimate goal of this project is to identify methodologies to detect the degree of corrosion on in-service guy anchors. It examines the extent and nature of the anchor corrosion problem, researches the state of the art and future trends in corrosion detection and identification, and discusses ways to prevent and mitigate anchor corrosion.
