Special model concrete cells, providing identity of tests for six armature samples, were prepared. Polarisation characteristics and impedance dependencies of the model cells, exposed to acid rain solution, were studied. It was established, that the inhibitor blend, containing sodium molibdate and calcium nitrate at equal mass ratio, is most effective for corrosion protection of steel armature. Inhibition efficiency of the blend is in 10–12 times higher than efficiencies of its single components. This clearly indicates a synergistic effect. An addition of the inhibitor to polyurethane injection composition, used for concrete construction repair, increases the adhesion between concrete and reinforcement exposed in corrosion environment. The use of synergism effect in the development of inorganic inhibitor mixtures allows significantly to reduce consumption of materials and to improve manufacturability of injection polymer compositions for reinforced concrete repair.
