Limitations of the use of concrete resistivity as an indicator for the rate of chloride-induced macro-cell corrosion [PDF]

, 2017
An experimental setup was designed to study the impact of concrete resistivity on the rate of chloride-induced reinforcement corrosion. Small pieces of mild steel were used to simulate pits (anodes) that form when chlorides come into contact with the ...
