Steel fibre reinforced shotcrete (sprayed concrete) is a vital factor for achieving long technical lifespan and safe performance for the support of hard rock tunnels. A large number of fibres must cross areas with large tensile stresses for the shotcrete to be efficient.Computed tomography (CT) is a laboratory testing technology based on X-ray scanning followedby digital image detection to visualize the material interior. This is here used ina mesoscale approach for investigation of in situ cored shotcrete samples containing full sizefibres and aggregates. For investigating the occurrence and orientation of steel fibres in shotcretethis method is much more efficient than the traditionally used electron microscopy studiesof sawn thin slices, which is time consuming, costly, destroys the samples and providelimited information. The newly developed method provide a complete and detailed descriptionof the fibre orientation within a cored shotcrete sample.
