In this study, effects of fibre aspect ratio (length/diameter) and aggregate size on flexural properties of steel fibre reinforced concrete and the connection with fibre distribution and orientation within the concrete matrix have been investigated. Hooked end steel fibres of length 60 mm with different aspect ratio of 65 and 80, at a dosage of 50 kg/m3 and two maximum aggregate sizes of 10 mm and 20 mm were selected for the experimental programme. Flexural performance was assessed through beam and slab tests at 28 day while compressive strength was also measured using cubes. X-ray Computed Tomography was employed for imaging cores taken from the slab specimens after testing and subsequent analysis of the positioning of fibres carried out by Insight Toolkit Software. The results show a remarkable improvement in flexural strength (up to 66%) when steel fibres are introduced while the combined effects of fibre geometry/aggregate size were observed to improve ductility.",
