Abstract: 
The experimental study herein described was conducted aiming to design UHPFRC with enhanced ductility and flowability. The influence of different type and dosage of steel fibres on the behaviour of UHPFRC was analysed. Steel fibers with different aspect ratio (l/d) were added, individually and blended, to the mixtures. The flexural strengths of all UHPFRC mixtures were measured. The concrete flowability was assessed using both the slump flow test and the V-funnel test. Conclusions are drawn in relation to the optimal addition of steel fibres, i.e., the one leading to the highest flexural strength and simultaneously ensuring self-compacting properties of the mixtures.
