Sažetak

This study aimed to elucidate the effects of incorporating basalt and banana fibres on the mechanical behaviour of ultra-high-performance concrete (UHPC). Two distinct UHPC groups were evaluated; the first group consisted of unreinforced control specimens, whereas the second group included fibre-reinforced specimens with systematically varied fibre volume fractions of 0,25; 0,50; and 1,00 % to assess the impact of fibre content. The fibres enabled a thorough assessment of their types and impact on UHPC performance. Beam-shaped specimens were cast with these fibre contents to facilitate three-point bending tests, enabling assessment of their response under flexural loading. The results conclusively demonstrate that incorporating 1,00 % basalt fibres yielded significantly improved performance compared to all other mix proportions, including those containing banana fibres or lower basalt fibre content. This outcome highlights the potential of basalt fibres as a valuable reinforcement strategy for enhancing the mechanical properties of UHPC, particularly its flexural resistance and energy-dissipation capabilities.
