Abstract

This paper investigates the impact of cement-based coatings on the endurance of Glass Fiber Reinforced Polymer (GFRP)-wrapped columns in maritime environments. GFRP materials offer remarkable durability and corrosion resistance, making them an attractive choice for marine structures. However, prolonged exposure to harsh marine conditions can still degrade their performance over time. Cement-based coatings present a promising solution to enhance the resilience of GFRP-wrapped columns by providing a protective barrier against chloride ingress, abrasion, and mechanical damage. Through a thorough review of literature, experimental studies, and theoretical analyses, this research explores the synergistic relationship between cement-based coatings and GFRP materials, elucidating their mechanisms of protection and durability. Practical considerations such as application techniques, performance evaluation methods, and maintenance strategies are also discussed. By advancing our understanding of how cementbased coatings can fortify GFRP-wrapped columns in maritime environments, this study aims to contribute to the development of sustainable and resilient coastal infrastructure practices.
