Embedded sensors for the monitoring of corrosion parameters in concrete structures
Corrosion of reinforcement is one of the main durability problems of concrete structures. The corrosion induces several structural damages which affect the serviceability and the safety of concrete structures. The structural risk is promoting the possibility of embeded sensors which could give alerts in order to repair the structure before reaching dangerous levels of damage. There are an increasing number of concrete structures that are being monitored in order to control their durability. However almost no results of the interpretation of the values obtained can be found in the literature. The experience until now shows the difficulty of interpretation of the data collected due to the influence of temperature and moisture on them and how to use these data to predict future evolution of the process. About the corrosion parameters to be monitored and evaluated, corrosion potential, concrete resistivity and corrosion rate (measured by the polarization resistance method, Rp), seem to be the most useful parameters to be correlated with the environmental parameters for the characterization of the corrosion process. In this paper, several examples of on site records of the corrosion potential, concrete resistivity and corrosion rates are presented. The results obtained allow correlating corrosion and environmental parameters.
