Effect of benzotriazole corrosion inhibitor in ordinary and high performance concrete

Technological advances have provided new ways of combating corrosion. Corrosion inhibitors are one means of protection for reinforced concrete structures. The effectiveness of commercially available inhibitor for concrete has been investigated. This study focuses on the effects of benzotriazole inhibitor on ordinary concrete and high performance concrete. The strength and durability property of different dosage of specimens without and with inhibitors on ordinary concrete and high performance concrete was compared. Corrosion tests such as Alternative Current (AC) impedance, Open circuit potential, Long term Potential Resistance (LPR) sweep, Custom sweep, and Half-cell potential were also conducted and compared with ordinary and high performance concrete without and with benzotriazole inhibitor. The inhibitor shows better performance strength, durability and good corrosive resistance.
