N2 - In this paper, the flexural performance of Fibre Reinforced Concrete (FRC) with an optimised spirally deformed steel fibre developed by the authors is evaluated experimentally. For comparison purposes, concrete specimens with commercially available steel fibres (hooked-end and crimped) are tested and included in the study. The research findings indicate that the optimised spirally deformed steel fibre considerably enhances flexural characteristics of concrete compared with existing fibres on the market. Moreover, the deflection-hardening response (even in the presence of wide cracks) can also be achieved even with low spiral fibre dosages common in practice. Therefore, such a composite, i.e. concrete reinforced with spirally deformed steel fibre, can be deemed as a structural material.
