Perspective for creating gradient concrete for electrocorrosion-resistant products and structures

Abstract

A large number of reinforced concrete products and structures are operated on the railways of the world, in particular in Ukraine and China. As a result of mechanical, electrical, temperature, and other aggressive influences associated with the operation of railway transport, reinforced concrete structures undergo intensive wear and tear, and their bearing capacity decreases. On electrified sections of railways, corrosion damage to reinforced concrete structures, cracking, and deformation occur more intensively than on non-electrified sections. Electrical leakage currents can lead not only to accelerated leaching of concrete, but also to the formation of cracks caused by electrocorrosion of steel reinforcement.
