Abstract	Many of today's ageing reinforced concrete structures have reached or exceeded their expected service life and a significant number of newer structures exposed to severe environmental conditions are showing premature deterioration within 20 years of construction (Mehta, 1991). Concrete structures deteriorate due to a number of processes such as electrochemical processes (i.e. corrosion of the steel - Photo 1), physical process (such as freeze thaw - Photo 2), chemical processes (such as chemical attack, sulphate attack, alkali-aggregate reaction, - Photo 3) and mechanical damage. These processes lead to a physical manifestation of either shrinkage or expansion of the concrete which then result in the cracking and spalling of the concrete. To date, the strategy has been repair and rehabilitation rather than replacement. However, repair not only has a more recent history, it does not have established codes which a proper design can be done.
