Thus it is important to repair the damaged reinforced concrete structures timely and prolong the service life of the structure. For the repair of marine R.C. structures, both the general performance of the repairing materials and the construction environment and matter of durability shall be considered. With the development of material technology and construction technology, various kinds of repairing materials and construction technology adapting to different marine environments have been developed. Some new repairing technologies commonly used for mari
