(TU Delft Materials and Environment) Koleva, D.A. (TU Delft Materials and Environment) van Breugel, K. (TU Delft Materials and Environment) Date 2017 Abstract This paper reports on the advantages and drawbacks of available test methods for the determination of chloride content in cementitious materials in general, and the application of Ag/AgCl chloride sensors in particular. The main factors that affect the reliability of a chloride sensor are presented. The thermodynamic behaviour of silver in the presence or absence of chloride ions is described and kinetic restrictions are addressed. The parameters that can affect the activity of chloride ions in the medium and/or the rate of ion exchange and dissolution/precipitation processes at the sensor’s surface are also considered. In this regard, the contribution of morphology and microstructure of the AgCl layer, binding of chloride ions and the compactness of hydration products around the chloride sensor are highlighted. The important parameters for a reliable sensor’s response are discussed and the possible causes of inaccuracies are evaluated Subject Ag/AgCl electrodecementconcretechloride sensorOA-Fund TU Delft To reference this document use: http://resolver.tudelft.nl/uuid:a2f8bcc8-d524-45eb-91e6-ff9e05c930d6 DOI https://doi.org/10.3390/s17112482 ISSN 1424-8220 Source Sensors, 17 (11) Part of collection Institutional Repository Document type journal article Rights © 2017 F.
