Abstract:
This thesis investigates accelerated chloride-induced corrosion of reinforced concrete intended for low- and intermediate-level radioactive waste (LILW) repositories. The study uses the impressed current (galvanostatic) technique to accelerate corrosion in concrete specimens exposed to a sodium chloride solution. Corrosion potential, concrete resistivity, and corrosion rate will be monitored using non-destructive electrochemical measurements, together with visual inspection of the reinforcement. The accelerated corrosion results will be compared with three-year natural corrosion monitoring data to improve the understanding of corrosion behaviour and assess the suitability of accelerated testing for studying the long-term durability of reinforced concrete structures in LILW repositories.
