Advanced Materials and Structures for Marine Infrastructure

This Research Topic aims to bring together cutting-edge research on environmental zoning, the development and performance optimization of high-performance corrosion-resistant materials, and the mechanical behavior and long-term durability of FRP-reinforced concrete structures for coastal and offshore regions. We invite submissions that address the dual challenges of resource scarcity and aggressive marine exposure through the integration of high-performance sustainable materials, such as low-alkalinity seawater sea-sand concrete and corrosion-resistant FRP materials, with optimized structural design methodologies. The overarching objective is to transcend conventional durability assessment and establish a holistic framework that synergistically co-optimizes constructability, long-term reliability, and environmental impact. This Research Topic particularly encourages investigations that bridge the gap between micro-scale material degradation mechanisms and macro-scale structural mechanical performance, with special emphasis on behavior under coupled environmental-mechanical loading conditions. We especially welcome contributions leveraging recent advances in durability degradation modeling, interfacial bond-slip characterization, and full life-cycle performance evaluation of FRP-reinforced concrete components. By fostering a dialogue among material innovation, structural mechanics (including seismic and fatigue resilience), and durability assessment methodologies, this Research Topic endeavors to provide informed material selection criteria and a robust theoretical foundation for the development of durable marine infrastructure.We welcome submissions on:- Low-alkalinity and sustainable cementitious systems for seawater sea-sand concrete (SWSSC): Development and characterization of low-alkalinity binders, high-volume supplementary cementitious materials, mix design optimization for chloride-rich marine environments, and strategies for crack control and permeability reduction.- Durable and corrosion-resistant reinforcement for marine structures: Hydrophobic FRP bars, FRP-steel composite bars, and surface modification technologies (e.g., fluorination, micro-nano texturing) for enhanced durability in high-alkalinity and high-salinity concrete pore solutions.- Interfacial bond-slip behavior and durability mechanisms: Experimental and theoretical investigations into the bond-slip relationship between FRP and SWSSC, including the interfacial degradation under coupled environmental-mechanical loading, and bond durability in marine exposure zones.- Structural performance and resilience of FRP-reinforced SWSSC components: Static, seismic, and fatigue behavior of beams, slabs, columns, and pile elements, with emphasis on the influence of extreme marine hazards.- Multi-scale durability modeling and service-life prediction: Deterioration models incorporating material aging factors (strength degradation of reinforcement, time-dependent concrete properties), marine environmental zoning (submerged, tidal, splash, atmospheric), and coupled multi-hazard actions (chloride ingress, alkaline attack, mechanical loading).- Life-cycle assessment and sustainable design frameworks for coastal and offshore infrastructure: Integration of durability-informed design, constructability considerations, and emerging technologies (e.g., prefabrication, structural health monitoring, digital twins) to achieve co-optimized reliability, environmental footprint, and life-cycle cost.We invite submissions of original research articles, authoritative review papers, and in-depth case studies that collectively advance the understanding and application of advanced materials and structures in marine environments.
