Experimental results on three types of HPFRCC reinforced with steel and polyvinyl-alcohol fibres subjected to dynamic tensile loading are presented. The tests were carried out on notched-specimens by means of a modified Hopkinson bar, a hydro pneumatic and universal apparatus for high, medium and low strain-rate respectively. From the experiments it was found that there is a significant enhancement in tensile strength with increasing strain-rates. The dynamic tests on HPFRCCs, for increasing strain- rates, show a remarkable decrease of post-peak strength and ductility with respect to the static tests.
