heal.abstract	The present study concerns the investigation of the protective effect of migrating corrosion inhibitors, against rebar corrosion, in specimens of repair fiber reinforcement mortars, in relation to these containing corrosion inhibitors. The strain gauge (SG) measurement technique was used for fast corrosion measurements, under anodic potential application in corrosive environment of 3.5% wt NaCl solution. The corrosion protection effectiveness was also tested by galvanic current measurements between different categories of specimens in order to estimate the galvanic corrosion between repaired and non-repaired areas. According to these investigations the positive effect of the migrating corrosion inhibitors in fiber-reinforced mortars against corrosion of the rebars is evident, providing a prevention of steel rebars' corrosion in the cases of repairing concrete structures. The presence of fiber reinforcement in repair mortar specimens prevents the microcracking effects, resulting in decrease of concrete cracking due to reinforcement corrosion. © 2002 Elsevier Science Ltd.
