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