Concrete and fiber reinforced concrete beams were tested in a drop-weight, instrumented impact testing machine. During the impact event, loads, deflections and strains were monitored. The modulus of rupture at high strain rates obtained in impact loading was up-to twice that observed at low strain rate (static loading). The influence of matrix mix proportions, relative humidity during curing and the type of fibers (steel, polypropylene and glass) on impact properties are presented.
