An evolution of distribution and orientation of fibres in the fibre reinforced self-compacting concrete during the casting process is an important matter as the final orientation and distribution of fibres can significantly influence mechanical properties of the structural elements. A two-way coupled model for flow of suspension of rigid solid particles in a non-Newtonian fluid with a free surface has been developed for such a purpose and is shortly presented in this paper. Several experiments using an apparent yield stress fluid, i.e. Carbopol® Ultrez 21 Polymer transparent gel, were conducted and analysed by means of digital image analysis. Orientation tensor fields coming from the digital image analysis were compared with the simulation to verify the ability of the model to properly represent the flow of the fibre reinforced self-compacting concrete
