Autonomous Sensor System for Corrosion Monitoring of Reinforced Concrete Structures

In this paper we present Corrochip©, an autonomous system for corrosion monitoring of reinforced concrete structures which is trademarked by Witeklab. This is an integrated sensor network which allows a non-destructive corrosion rate monitoring of the reinforcement at different parts of the structure, even at buried and submerged ones. Corrochip© is based on an economic, simple, reliable and durable technology, which makes its implementation viable on new and repaired reinforced concrete structures (RCS). Furthermore, no technical personnel are needed because the acquisition, storage and transmission of data is autonomous. In this way, it is possible a remote corrosion assessment of several RCS. In this work we report the most relevant results obtained from the Corrochip© implementation and validation in scaled-down prototypes and real RCS. It is shown the ability of the system to autonomously manage a large sensor network and to clearly detect emerging corrosion processes
