Part 1 of this article was published in New Zealand Concrete Construction, Sept 1989 (IRRD 826648). In Part 2, the author examines the options for repairing deteriorated reinforced concrete structures. The range of solutions can be summarised as follows: (a) leave alone and accept the existing state of deterioration, monitor the deterioration state with time and provide structural propping as required; (b) apply barrier coatings to inhibit further ingress of the environment; (c) breakout damaged areas to the reinforcement steel or beyond, treat the steel, restore with a high quality patch material and apply a barrier coating to the damaged and surrounding areas; (d) cathodically protect the reinforcement, and (e) cut out the member and replace with an improved protection specification. He goes on to consider the residual strength of deteriorated structures and the various tools available for diagnosing corrosion.
