Effect of Stray Current on Corrosion and Calcium Ion Corrosion of Concrete Reinforcement

open access: yesMaterials, 2022
The construction of subways, hydroelectric stations and water substations is exposed to stray currents, which can accelerate concrete corrosion. The influence of stray currents on reinforced concrete structures is unclear. In this paper, the influence of concrete strength grade, reinforcement diameter and stray current intensity on the extent of ...
