Practical circular economy applications of recycled and industrial steel fibres in structural concrete

Dr Sakdirat Kaewunruen, Reader in Railway and Civil Engineering, University of Birmingham

As a secondary material recycled from tyres, Recycled Steel Fibre Reinforced Concrete (RSF) aims to replace industrial steel fibres (ISF) to improve concrete matrix‘s severability, fracture toughness, and residual tensile stress. Despite the increasing attention on the mechanical properties of this material, RSF concrete’s influence on structural component strength is still neglected due to a lack of sufficient and reliable experimental data. This presentation will highlight new research outcomes that will enhance structural applications with ISF and RSF in construction industry.
