Both deterioration due to corrosion and excessive loadings caused by over traffics or earthquakes are the major causes of loss of function of reinforced concrete structures all over the world. Thus. improved. cost effective and reliable techniques and materials are urgently needed to repair and strengthen the deteriorated and damaged concrete structures. The most conventional techniques have many limitations to be overcame. However. these techniques are much more economical than rebuilding. yet conventional methods are costly, timeconsuming. and often ineffective. Therefore. there is a need to develop new materials and techniques capable of rapidly and cost-effectively rehabilitating civil engineering structures. R&D works on the new and more economical techniques for rehabilitating reinforced concrete structure elements such as columns, beams. and walls using advanced composite materials began several years ago. The most R&D and field application projects have concentrated on concrete column repair and reinforcement. In this report. recent R&D works and commercialized techniques on concrete structure repair and strengthening using advanced composites will be reviewed.
