| Description |
Sensors are involved in the corrosion monitoring and structural monitoring of concrete structures. In this investigation
attempts have been made on the corrosion monitoring of concrete structures by employing embeddable reference sensor.
Alkaline manganese dioxide (MnO2) sensor was fabricated in the laboratory as suitable as an embeddable use into the concrete
structures. The electrochemical stability of sensor in concrete environments was examined in saturated calcium
hydroxide solutions, a synthetic concrete pore solution and an extracts obtained from ordinary Portland cement. Sensor
is embedded into the concretes and the performance was studied in the absence and presence of chloride ions for the exposure
period of 18 months. Polarisation behaviour and impedance characteristics of the sensor in mortar were carried out in
three aqueous solutions namely distilled water, 3% NaCl solution and natural sea water. This investigation covers the tests
in solutions representing concrete environments, electrochemical studies in mortar and the long-term exposure studies in
concrete.
