Summary
Conventional concrete structures face persistent challenges from mechanical degradation, corrosion-induced deterioration, and extreme loading events, particularly in marine environments and seismic zones where performance demands are exceptionally high. Fiber-reinforced concrete (FRC) and fiber-reinforced polymer (FRP) strengthening technologies have emerged as transformative solutions that fundamentally enhance the inherent properties of concrete. FRC substantially improves tensile strength, flexural toughness, impact resistance, and crack control of cementitious materials, while fundamentally enhancing durability by limiting crack propagation and reducing permeability—a critical advantage for marine concrete structures exposed to chloride ingress. FRP strengthening techniques, including externally bonded reinforcement, near-surface mounted systems, and confinement, work in direct synergy with concrete substrates to rehabilitate and upgrade existing structures, significantly enhancing seismic resilience, load-bearing capacity, and ductility.
This Special Issue aims to present cutting-edge research on FRC and FRP-strengthened concrete, emphasizing cementitious materials development and concrete structural applications that align with the journal's core scope. We invite contributions bridging fundamental cement and concrete science with engineering practice, addressing concrete performance enhancement, durability assurance, and structural resilience. Interdisciplinary approaches integrating experimental investigations, numerical modeling, and artificial intelligence-based prediction are particularly encouraged.
Suggested themes include:
· Fiber-reinforced cementitious composites: advanced fibers, UHPC, mechanical properties, and durability in marine environments
· FRP strengthening of concrete structures: EBR, NSM, prestressed systems, flexural/shear strengthening, and seismic retrofit
· FRP confinement of concrete: confinement mechanisms, stress-strain models, and column behavior under various loading conditions
· FRP bars as internal reinforcement: bond behavior with concrete, flexural/shear performance, and durability
· Durability of FRP-concrete systems under environmental exposure
· AI-based predictive modeling and sustainability assessment of FRC and FRP-strengthened concrete systems
We look forward to receiving your valuable contributions advancing the science and practice of fiber-reinforced and FRP-strengthened concrete technologies.
