Summary
As a growing number of concrete infrastructures enter long-term service, structural cracking, spalling, leakage, and durability deterioration have become increasingly prominent due to environmental exposure, mechanical loading, material aging, and other factors. High-performance cement-based repair materials, owing to their favorable mechanical properties, interfacial compatibility, durability, and constructability, have become an important material system for the repair and performance restoration of existing concrete structures. In recent years, the rapid development of ultra-high-performance concrete (UHPC), fiber-reinforced cementitious composites, polymer-modified materials, and functional repair materials has placed higher demands on mixture optimization, interfacial bonding, and long-term service performance of repair systems.
This Special Issue aims to showcase the latest advances in high-performance cement-based repair materials, with particular emphasis on optimized material design, microscopic characterization, durability, and innovative applications. It seeks to promote the integration of material design, interfacial mechanism studies, and engineering repair practices, while accelerating the practical implementation and industrial development of high-performance, low-carbon, and intelligent repair technologies.
Research topics include (but are not limited to):
· Rapid-hardening, early-strength, and low-shrinkage cement-based repair materials
· Fiber-reinforced and high-toughness cement-based repair materials
· Low-carbon and solid-waste-based cement-based repair materials
· Magnesium phosphate cement-based repair materials
· Self-healing, self-sensing, and multifunctional cement-based repair materials
· Intelligent design and performance optimization of cement-based repair materials
· Interfacial modification technologies using polymers, nanomaterials, and other modifiers
· Formation, evolution, and regulation mechanisms of repair interfacial transition zones
· Interfacial bonding, fracture, and damage evolution behavior of repair systems
· 3D printing, digitalization, and intelligent repair technologies
· Durability and long-term service performance of repair materials under complex environmental conditions
· Engineering applications and case studies of repair technologies for bridges, tunnels, roads, hydraulic structures, marine infrastructure, and energy facilities
Keywords
