One of the methods for corrosion protection of reinforced concrete is the use of migrating corrosion inhibitor as an admixture in repair mortars. The admixture must be effective for corrosion protection and compatible with polymers added to repair mortar to improve properties of fresh and hardened mortar. This paper presents experimental results on compatibility of a migrating corrosion inhibitor added to two repair mortars based on an inorganic binder modified with polymers. The influence of a migrating inhibitor on the properties of fresh and hardened mortars was tested. The effectiveness on reinforcement corrosion protection has been tested according to ASTM G 109. Test results prove that the investigated migrating inhibitor is compatible with repair mortars and that it delays corrosion of the reinforcement.
