Abstract: This paper presents the results of an experimental investigation on steel fiber refractory concrete performed under static and impact loading under high temperatures. For the impact tests a modified Hopkinson pressure bar (MHPB) was used. A spherical steel striker driven by gravity was employed and the apparatus was instrumented with solid-state strain gauges allowing the measurement of forces acting on the concrete and its deformation during the impact. A static compression and flexural test was performed to compare the concrete’s fracture behavior when subjected to long and short term loads. Fiber volume fractions of 0.7% and 1.0% were used as reinforcement in a self-compacting matrix. The impact and static tests were performed at room temperature after the specimens being exposed to firing temperatures of 110 oC and 650 oC.
