Abstract:The corrosion of reinforcing steel in highway structures results in maintenance and replacement costs in the United States that are measured in billions of dollars. The use of deicing salts has resulted in the steady deterioration of roadway bridge decks due to corrosion. One method to reduce corrosion is the use of corrosion-resistant alloys. A high-strength, high chromium reinforcing steel, MMFX Microcomposite steel, is evaluated for corrosion resistance, mechanical properties, applicability for structural applications, life expectancy and cost effectiveness. The steel is compared with conventional mild steel reinforcement, and epoxy-coated reinforcement. Principal emphasis is placed on corrosion performance of the steel, which is evaluated using rapid macrocell tests of bare and mortar-wrapped reinforcement and initial test results for Southern Exposure and cracked beam tests. Life expectancy and cost effectiveness are evaluated based on experience and costs in South Dakota, combined with laboratory results for the chloride content required for corrosion initiation and the rate of corrosion in cracked concrete.
