Selection of cathodic protection systems for reinforced concrete structures

Cathodic protection is a corrosion management strategy for deteriorating reinforced concrete structures or it can be used as preventative measure in situations where corrosion may be expected during the service life as a result of the environmental exposure conditions. The technology has advanced over time. There are now a number of different systems that can conveniently be considered in three categories, including impressed current cathodic protection (ICCP), hybrid cathodic protection (HCP), and galvanic cathodic protection (GCP).

A pathway to thickness measurement locations (TMLs) digitalisation.

Permanently installed sensors provide more accurate results compared to conventional inspection due to their consistent positioning and coupling. However, due to their cost, they are normally used for monitoring critical areas for corrosion rate estimation. There are hundreds of thousands of thickness measurement locations (TMLs) on the site, making it challenging to monitor all of them.

We propose an alternative approach that combines passive sensors and a different data collection method to enable a cost-effective, consistent, and deployable solution. In this work, we present how the handheld data collector, robotics, and online solutions work together to address different applications with accessibility and inspection frequency.
