Abstract
Some embodiments are directed to a system for assessing chloride concentration at one predetermined area of a porous or composite material, such as a reinforced concrete structure, including a sensor embedded in the predetermined area of the material, an analyzer connected to the sensor, and a processing module connected to the analyzer. The sensor includes two facing or coplanar electrodes, an intermediate layer arranged between the electrodes, the intermediate layer being in contact with the material of the predetermined area of the structure and including calcium aluminates. The analyzer is configured to apply an alternate current between the electrodes and output an impedance value or capacitance value of the intermediate layer. The processing module is configured to compute a chloride concentration assessment in the predetermined area of the material based on the impedance value or capacitance value outputted by the analyser.
