CATHODIC PROTECTION OF STEEL REINFORCED CONCRETE BY CONDUCTIVE EPOXY PAINTS IN MARINE ENVIRONMENTS

Anodes are critical component of cathodic protection systems. As part of this effort, three different anodes were tested in a cathodic protection system that was designed and constructed to prevent further corrosion of reinforced concrete. This anodic system includes an electrically conductive coating composition applied in fluid form over an outer surface of the concrete mix. The composition f...

Experimental Investigation of Corrosion Cracking in Reinforced Concrete Beams Containing Nano Wollastonite

Cracking of the concrete cover due to corrosion is defined as the serviceability limit state of reinforced concrete structures. This study evaluated the influence of a mineral admixture i.e. nano wollastonite on corrosion performance and serviceability of reinforced concrete structures by performing an accelerated corrosion test on ten reinforced concrete beams under a sustained load. To do so,...

Corrosion and Cathodic Protection in Underground Piping Systems

THE GALVANIC CELL The major corrosion concern in the water works industry is “galvanic” corrosion. Galvanic corrosion takes place due to current flow in a “galvanic cell” which is defined as (1) two dissimilar metals, an anode and a cathode, (2) in electrical contact with each other and (3) a common electrolyte. A galvanic cell is produced when the pipeline components come in contact with the s...
