Automatic system for monitoring corrosion of steel in concrete

摘要

Corrosion of embedded steel in concrete is the main deterioration mechanism in reinforced concrete structures. Electrochemical techniques are powerful tools for evaluating the steel behavior in cementi-tious materials in laboratory and in the field. However, the number and frequency of measurements, and their accuracy are always a challenge for researchers and engineers. In this project, a measurement unit and a flexible program has been developed with LabVIEW 6.1 to allow automated measurements using a variety of electrochemical techniques.
