Abstract: Deterioration of concrete structures throughout the world and the cost of their repair and rehabilitation have become a major concern to engineer and researchers in recent years. Almost cases the repair costs can be twice or more of the original cost. For example, in Canada, it is estimated that the cost of repair of parking garages is in the range of 6 billion dollars, and over 74 billion dollars for all concrete structures. The estimated repair cost for existing highway bridges in the USA is over 50 billion dollars, and 1-3 trillion dollars for all concrete structures. In Europe, steel corrosion has been estimated to cost about 3 billion dollars’ year. Excessive corrosion problem also exists in Arabian Gulf countries (Benmokrane et al., 1998). Organizations, private industry and university researchers are seeking ways to avoid the corrosion problem and thereby eliminate, partially or totally, burden of never ending repair costs. One preferred solution, which has assumed the status of cutting edge research in many industrialized countries, is the use of fiber reinforced polymer (FRP) rebars in concrete.
FRP reinforcement has an advantage over steel in that it has high corrosion resistance and a high strength to weight ratio, thus for structures built in or close to seawater or at similar corrosive environment. They are also non-conductive for electricity and non-magnetic.
