Abstract: 
The impact resistance of ultra high strength concrete as an alternative material for driven piles was investigated by subjecting concrete cylinders to series of impacts. The type and amount of steel fibres and concrete composition were varied. Impact resistance was characterized by the number of impacts applied before the ultrasonic pulse velocity decreased by 10%.The results show that the impact resistance of ultra high strength concrete is mainly determined by the type and amount of steel fibres rather than binder composition. Volumetric replacement of micro steel fibres by larger fibres (straight and crimped) resulted in loss of impact resistance.
