This chapter deals with the strategies for repair of reinforced-concrete structures damaged by carbonation or chloride-induced corrosion of the reinforcement, and outlines the most common methods. Details of conventional repair and electrochemical maintenance methods are reported in Chapters 19 and 20. The repair of prestressed concrete structures is outside the scope of this book.

It is thus apparent that care must be taken when selecting materials for the deep patch repair of reinforced concrete members to ensure that the material is structurally compatible with the substrate.

Cathodic protection of reinforced-concrete structures exposed to the atmosphere was apphed for the first time to bridge decks contaminated by de-icing salts by R. F. StratfuU in California in 1973 [1,2]. In the years following, design and protection criteria were elaborated, as well as power supply and monitoring systems completely different from those used for cathodic protection of buried steel structures or structures operating in seawater. Above all, it was proved that cathodic protection was a rehable repair technique even in the presence of high chloride contents, where traditional systems of rehabilitation are inefficient or very costly.

As Y. Ohama says the early deterioration of reinforced concrete stmctures has been a big social problem in the world in recent years and he continues the future growth of sustainable concrete-polymer composites such as polymer modified mortar and concrete, and polymer mortar as repair materials is globally expected . P. Seidler states innovations cannot be forecasted innovations need firstly leisure time and thus money . It will be important for the development of the field polymers in concrete that the future technical trends will be well defined and that a good balance between time and money could be achieved.

Repair of systems for potable water treatment Water treatment plants are built of reinforced concrete and processes employed in water ptuifi-cation cause breakdown of concrete. These processes include preparation of coagulant and its mixing with water, chlorination of water, and preventive bactericidal treatment of reservoirs. Leakage of water, especially at sites of wall and floor joints, is frequently observed. 

A good review of strengthening of reinforced concrete structures is given by Ballinger, Maeda and Hoshijima [216]. Repair and strengthening of concrete structures are discussed [217-220] as is the use of carbon fiber strands and rods or bars [221 223]. Mitsubishi...
