Abstract/Summary In this study X-ray imaging is used to investigate the mechanisms of fracture in fibre reinforced concrete. The investigation looks at the performance of discrete end-hooked fibres crossing a cracking plane at various angles and loaded normal to the plane. The angle of a fibre crossing a crack is found to be an important parameter in determining the mode of failure and bending of the fibres were observed up to approximately 5 mm into the matrix from the fibre exit point. The tests show a probability that some fibres pullout from longer embedded side under Mode I fracture. In the non-destructive observation procedure presented here, the internal actions of the fibres at the various stages of loading can be determined. X-Ray imaging is shown to be a valuable tool in understanding steel fibre-concrete behaviour.
