PhD Title: Monitoring the interaction of multiple deterioration mechanisms in concrete

Supervisors: Dr. D. McPolin & Dr. N. Holmes

The primary aim of this project is to develop a comprehensive understanding of the boundaries in which corrosion of
reinforcement in reinforced concrete can occur when exposed to chloride ions, carbonation and sulphate. These will be examined both singularly and in combined action. This concept is to be explored in concretes manufactured with a combination of cementitious materials. The project will explore if the current design codes are valid for the effects of combined deterioration mechanisms.

Qualifications:
