Detection of Corrosion in Reinforcing Steel Bars using Microwave Dual-Loaded Differential Modulated Scatterer Technique

Abstract

Detection and evaluation of corrosion in reinforcing steel bars (rebars) commonly used in cement-based structures is an important ongoing concern. Embedded sensor technologies hold promise for this purpose. In recent years, modulated scatterer technique (MST) has shown great potential as an embedded sensor technology. The first step in evaluating the potential of embedded MST for rebar corrosion detection is to evaluate its potential for detecting the presence of subtle corrosion in a rebar. This short paper investigates the measurement potential for a dual-loaded differential MST approach for detecting relatively subtle corrosion in a steel rebar.
