Key Points

  • This research aims to evaluate the structural performance of recycled tyre steel fibre reinforced composites in urban concrete applications.
  • Evaluated recycled tyre steel fibres at material and full-scale urban concrete elements.
  • Assessed the effects of short and long fibres on post-cracking and deformation response.
  • Measured fibre content and orientation's impact on flexural behaviour through inductive measurements.
  • Short recycled tyre steel fibres improved early post-cracking behaviour.
  • Longer fibres enhanced large-deformation response, leading to improved post-peak stability.
  • Recycling tyres for steel fibre reinforcement reduced embodied carbon by approximately 98% compared to industrial standards.

Abstract

• RTSF were evaluated from material scale to full-scale urban concrete elements. • Short RTSF improved early post-cracking, while longer fibres enhanced large-deformation response. • Hybrid RTSF improved post-peak stability at full scale despite lower beam-scale toughness. • Inductive measurements confirmed the role of fibre content and orientation on flexural behaviour. • RTSF reinforcement reduced embodied carbon by up to ∼98% vs the industrial reference.
