Overview

Review demonstrates that hybridizing steel fibers with surface-treated nanocarbons enhances concrete strength and self-sensing, indicating an optimal design for smart infrastructure.

Key Points

  • To critically evaluate how integrating piezoresistive fibers—specifically silane-treated graphene nanoplatelets, carbon nanotubes, and metallic fibers—affects both the mechanical performance and self-sensing capabilities of ultra-high-performance concrete.
  • Critically reviewed and compared the integration of silane-treated graphene nanoplatelets, carbon nanotubes, and metallic fibers in ultra-high-performance concrete matrices.
  • Analyzed electromechanical sensitivity alongside mechanical cohesion, dispersion characteristics, and macro-crack bridging mechanisms.
  • Individual conductive nanomaterials enhance electrical conductivity for structural health monitoring but frequently suffer from dispersion challenges that degrade mechanical cohesion.
  • Hybridizing steel fibers with silane-treated nanocarbon fillers yields superior strain-hardening and flexural toughness through macro-crack bridging while maintaining a stable conductive network for real-time stress and deformation sensing.
