Concrete matrix samples with steel fibres embedded into concrete under different angles were fabricated and tested for pull-out test, pull-out force versus pull-out fibres length diagrams were obtained. Microscopic investigations of the samples after rupture were carried out and fibres canal geometrical parameters were measured. On the basis of microscopic investigations and pull-out diagrams mechanical behaviour of straight steel fibre with different inclination angles was thoroughly analysed. Average energy of the pull-out test for each fibre inclination angle was obtained.
