- Аннотация: In inhibitory protection of reinforced concrete structures, one often has to deal with rusted reinforcing steel. Therefore, studies on the effect of corrosion inhibitors (contact and migrating ones) on the corrosion-electrochemical behavior of rusted reinforcing steel in concrete is a mandatory stage in the development of efficient anticorrosion formulations. It was previously shown in experiments on stripped reinforcing steel that some phenol derivatives effectively prevented corrosion initiation in simulated chloride-containing pore fluid. In this work, we studied the protective properties of catechol (IFKhAN-85) toward rusted reinforcing steel in concrete. Using corrosion-electrochemical methods, it was shown that incorporation of 1% IFKhAN-85 with tempering water into concrete containing 3% NaCl provides a passive state of rusted reinforcing steel under severe conditions of moisture capillary suction and permanent anodic polarization. External treatment of the concrete surface of samples made using rusted reinforcing wire with 3% IFKhAN-85 solution converts steel to the passive state.
