    Fibre reinforced concrete is a type of concrete which, unlike conventional concrete in its structure also contains discontinuous high tensile strength fibres. Thanks to them, it has significantly ... better mechanical properties than ordinary concrete. In addition to the need for uniform fibre distribution in concrete, a very important parameter, which directly influences the mechanical properties of fibre reinforced concrete, is the orientation of each individual fibre. The need for a better understanding of the influence of fibre orientation on mechanical behaviour, anisotropy of material and progression of damage, puts in centre microstructural analysis. With this development and huge improvements in X-ray tomography, 3D analysis of fibre orientation has become possible by testing concrete samples. For the purpose of this study, the samples of reinforced concrete with different proportions of industrial and recycled steel fibres were tested. For the need of fibre orientation analysis, samples of reinforced concrete were examined by computer tomography and 3D analysis of images was performed. This is the first time that this kind of analysis was performed for hybrid concrete, where tomography is used for simultaneous detection of geometrical properties of two different types of steel fibres. The aim of the study was to determine the influence of orientation and number of fibres on the post-cracking behaviour of hybrid fibre reinforced concrete.
