abstract = "We propose magnetic sensing as a non-destructive method to monitor steel corrosion in concrete. GMR sensors show promise for this application. Initial experimental tests showed that the magnetic fields can be sensed readily, even through concrete. The residual magnetic field emitted by a piece of stock reinforcing steel bar can be significant, comparable to that of a bar magnet. Test data show that signal variability is highly sensitive to sensor type and input voltage. Initial results show that GMR sensor data are capable of distinguishing between passivated and corroding reinforcing steel bars. 2008 Taylor & Francis Group.",
