Corrosion of steel in soil environments was monitored by thin film electrical resistance sensor having high sensitivity for corrosion rate measurement. The results show that this sensor made it possible to predict the long-terrn corrosion behavior of steel expressed by a kinetic curve obeying power law within a short period. Moreover, the effect of soil resistivity on corrosion rate measurement was eliminated using this sensor. (C) 2007 Published by Elsevier B.V.
