Abstract

The deteriorating conditions of reinforced concrete bridges demands new and innovative technology for the repair and rehabilitation of these bridges. The damage caused by the corrosion of steel reinforcement is a prime factor of bridge deterioration. Cathodic protection is emerging as the leading method for the protection of these damaged bridges. The recent innovation of conductive concrete has led researchers to consider using this new concrete matrix for cathodic protection. This study determines the feasibility of conductive concrete for cathodic protection.

Four test slabs were cast with conventional reinforced concrete specified by the Michigan Department of Transportation (MDOT) for bridge decks. Steel electrodes were placed on these conventional concrete slabs with a conductive concrete overlay. Conductive concrete is a proprietary concrete matrix which generates an electrical charge through the overlay. Once the concrete slabs were allowed to cure, the slabs were monitored to determine the effectiveness of the conductive concrete overlay for cathodic protection.
