Improvement of superficial protection of steel concrete supports of the contact network against corrosion

Abstract

The influence of different water-repellent rendering compounds for steel concrete supports of a contact network on change of their electric resistance and water absorption is under study. It is shown that the domestic production "Silol" has the best parameters on these indices.
