A theoretical analysis of the causes, affects, repair and rehabilitation of concrete
corrosion in estuarine and terrestrial environments.


One of the fundamental concerns for the long term serviceability and lifespan of reinforced concrete is the potential risk of the steel reinforcing bars exposure to corrosion. This report will provide a comprehensive analysis of concrete corrosion as applicable to three case studies located in estuarine and terrestrial environments, in terms of three main categories:

· causes and mechanisms of reinforcement corrosion
· structural effects and damage
· appropriate methods of protection and repair

Due to the scope of this project it was not feasible to personally conduct laboratory experimentation and on site diagnostic testing of these structures. Therefore, we worked in conjuction with a licenced engineering company, GHD, who agreed to aid in collection of data and materials. All three case studies examined in this report were past commissioned projects of GHD.

After reviewing an extensive range of research material and test results, various remedial approaches were discussed for use on the investigated structures, with one approach being
selected as the recommended mode of choice. Due to the differing environment surrounding these structures, and the variations in cause of corrosion, each recommended repair option was different and individually suited to the structures needs and circumstances.
