Abstract

To develop a sustainable and durable rebar on different elements of the RC as a corrosion control system in regions where corrosion is the leading risk for the infrastructure system. The outcome of this research leads to a comprehensive report that provides methods, testing results, peer review papers, conference proceedings, and guidance for the utilization of rebar for corrosion control actions in RC, capable of long-term performance in harsh corrosive environments (deicing cycle conditions). Workforce development will also take place through a series of outreach activities targeting the broader audience of corrosion, civil, and materials engineers, and potential industrial partners to increase their awareness of the importance of developing new materials for durable transportation infrastructure. Through a range of characterization techniques, it became evident that these coatings exhibited varying degrees of corrosion resistance, primarily due to the barrier effect exerted by the distributed particles when exposed to an aggressive environment (3.5\% NaCl solution) over several weeks. The presence of MoS2 powders appeared to contribute to the creation of sacrificial materials that might induce the formation of semiconductors with capacitive-like behavior, ultimately influencing corrosion control through a mass transfer mechanism barrier. Furthermore, the absorption of water revealed insights into how these particles function within the polymer matrix and the effectiveness of establishing a physical barrier as part of the dispersion process.
