Integrated Sensor Network For Monitoring Steel Corrosion In Concrete Structures, José Enrique Ramón-Zamora, José Manuel Gandia-Romero, Román Bataller, Ana Martínez-Ibernón, Isabel Gasch, Juan Soto

International Conference on Durability of Concrete Structures

The developed Integrated Sensor Network (ISN) allows a non-destructive monitoring of the rebar condition at different parts of the structure. The corrosion sensor allows the accurate determination of the corrosion rate (µm/year). Moreover, additional sensors are integrated in order to detect relevant changes in the concrete electrochemical condition.

The ISN has been published as an international invention patent (reference number WO 2016/177929 A1). The system is based on an economic, simple, reliable and durable technology, which makes its implementation viable on new and repaired reinforced concrete structures (RCS). Therefore, it is also possible monitoring non-accessible parts such as deep foundations …

Monitoring Historic Concrete And Associated Cementitious Repair- A Case Study Of Boathouse 4, Portsmouth Historic Dockyard, Uk, Ahmed Alwaal, Stepanie Barnett, Robert Inkpen, Linley Hastewell

International Conference on Durability of Concrete Structures

This study presents a method of monitoring historic concrete and associated repairs. A case study of Boathouse 4, Portsmouth Historic Dockyard, UK is presented. Boathouse 4 is an iconic building within Portsmouth Historic Dockyard which was constructed during the 1930’s rearmament period. It was used during World War ll to construct the three-man midget X-Craft submarine. The building was restored and converted into a Boatbuilding Skills Training Centre in 2015. A field investigation was conducted to analyse the concrete damage and to monitor microscale changes to the surface of the original concrete and repairs over a period of three years. …
