Sensor Systems for Corrosion Monitoring in Concrete Structures

Sensor Systems for Corrosion Monitoring in Concrete Structures

It is a need of permanently embedded corrosion monitoring devices to monitor the progress of corrosion problems on a new or existing reinforced concrete structures before embarking on repair or rehabilitation of the structures. Numerous devices are available for investigating corrosion problems, bec...
