ABSTRACT:
A method of protecting reinforced concrete structures comprising of applying a protective cathodic coating containing a non-corroding metal and an electrochemically active material on concrete wherein the protective coating is formed by thermally spraying a mixture of said non-corroding metal such as a valve metal and said electrochemically active material. The coating may also be formed by applying a precursor of the electrochemically active material and a metal-containing layer to concrete, then anodically polarizing said metal layer to convert the precursor into an electrochemically active material.
