Structural Health Monitoring for Reinforced Concrete

PhD defence, Friday 10 June. Jaamac Hassan Hire

Jaamac Hassan Hire

During his Industrial PhD studies, Jaamac Hassan Hire has researched new techniques for corrosion monitoring in reinforced concrete structures. Reinforced concrete is the most used material in the world. In general, reinforced concrete is a durable material that can withstand a large range of severe environments, including marine and industrial conditions. Even though most structures show good long-term performance and high durability, there are still many premature failures resulting from reinforcement corrosion. Today, the corrosion assessment of structures is mainly performed through schedule-based visual inspection, which is labor-intensive, inaccurate, costly and may be untimely. Therefore, the PhD project proposes a design of a self-powered wireless corrosion monitoring system.

The developed sensor is based on a novel piezoelectric (electro-mechanical) principle. Furthermore for long-term powering of the system, a practical methodology to harvest energy from the corrosion process itself is presented.

The PhD study was completed at Department of Electrical and Computer Engineering, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
