STEEL REINFORCEMENT BARS IN CONCRETE CATHODIC PROTECTION

Steel reinforcement bars are compatible with concrete because they provide strong tension capacity to the structure and concrete usually provides an excellent corrosion protection for steel. The corrosion protection is the result of the formation of a passive oxidized film on the surface of the metal by highly alkaline Portland Cement contained in concrete. The passive film can be compromised by excessive amounts of chloride or other corrosive ions and gases or the metal inside concrete is not sufficiently encased by concrete.

The cathodic protection can be applied for both new structures before pouring the concrete and corroded structures to stop corrosion or completely repair the concrete.

Our company offers both galvanic (with sacrificial anodes) and impressed current cathodic protection system for all type of concrete structures. Our experienced team can design, procure, install and commission the system all the way through.

The galvanic anode manufactured by our company is called CP-X, it is zinc cored anode surrounded by highly alkali cementitious porous mortar which inhibits the passivation of the zinc through its design life.

We can also provide ICCP system using titanium mesh anodes that is similar working technic in any ICCP system; anode, cathode, the same electrolyte (which is concrete here) and electrical path.
