Evaluation of Concrete Durability and Corrosion Resistance of Concrete Structures in Marine Environments

This project will evaluate the effectiveness of various corrosion inhibiting measures that have been proposed for use by the Hawaii DOT. A field study will be conducted to investigate existing structures for chloride intrusion, permeability, and progression of the electrochemical reaction. A laboratory study will be used to identify the mixture proportions that will optimize the effectiveness of each of the corrosion inhibitors investigated. The laboratory study will also investigate the quantity and composition of the corrosion products at different stages with Raman spectroscopy. The most promising corrosion inhibiting methods identified in the laboratory study will be used in exposure slabs constructed for long-term monitoring of corrosion resistance.
