This study investigates the characteristics of self-compacting concrete (SCC) reinforced with recycled fibres and their combination with polypropylene fibres, which can be applied to build protective structures. The split Hopkinson pressure bar (SHPB) method was used to sub-ject the mixtures to high strain rates in the range from 140 to 200 s⁻¹, corresponding to impact loads. It was found that the strain rate sensitivity of both types of mixtures was comparable. The failure pattern confirmed the role of fibres in carrying the loads for strain rates below around 100 s⁻¹ .
