Jesse Curtis – Caribbean Project Case Studies | NEx Workshop

🎤 Speaker: Jesse Curtis, P.E. - Technical Sales & Engineering Manager, MST Rebar 📍 Presented at the NEx Workshop during the ACI Concrete Convention 📌 Rosemont, IL – April 1, 2026 This presentation examines the application of GFRP reinforcement in concrete structures constructed locally sourced unwashed sands in coastal regions. In several Caribbean projects in Guyana, Saint Kitts and Nevis, and the Bahamas, concrete production relied on local aggregates that can contain elevated chloride levels due to marine exposure and salt contamination. Such conditions significantly increase the risk of corrosion in conventional steel-reinforced concrete, leading to premature deterioration and high maintenance demands. The presentation highlights case studies where GFRP bars were selected to mitigate chloride-induced corrosion risks in aggressive marine environments. Because GFRP reinforcement is non-corrosive and immune to chloride attack, it provides a reliable alternative when seawater exposure or chloride-contaminated sands are present, or where full washing and strict material control may be challenging. This session is part of the NEx Workshop, co-sponsored by ACI COMMITTEE 243: “Application and Challenges for Concrete with Saline Water, Dredged or Dune Sand.” The ideas expressed in this seminar are those of the speakers and do not necessarily reflect the views of NEx, ACI, or its committees.
