Abstract: A modified version of ASTM C 1550 was used to study the impact behavior of fibre reinforced concrete. Specimens, in the form of circular plates, with a diameter of 650 mm and a thickness of 60 mm were prepared using plain high strength concrete (HSC) with a compressive strength of about 80 MPa, steel fiber reinforced HSC, and synthetic fiber reinforced HSC. Some panels were also reinforced with welded wire mesh. The panels were supported on three symmetrically located points, and were subjected to impact loading at their centers using a large, instrumented drop weigh impact machine. It was found that the failure modes under impact loading were similar to those under static loading, though the peak loads were higher under impact. It was found that the steel fibers led to a higher increase in toughness than the synthetic fibers. For the panels that contained the wire mesh, the fracture behavior was strongly dependent on the exact position of the mesh (i.e., whether the impacting hammer was located over a mesh opening, or over the intersection of two wires).
