Abstract: The behaviour of high performance steel-fiber reinforced concrete under dynamic compression has been experimentally investigated. Two concrete grades (C100/120, C200/240), based on cementitious mixes containing quarts sand and bauxite, respectively, have been examined using 40mm and 60mm cubic specimens. Three testing conditions have been implemented, i.e., static, intermediate strain-rate and higher strain-rate, where for the latter Hopkinson bar techniques have been employed. The entire stress-strain curves have been obtained. The results concerning strength and ductility show that these concrete types exhibit a distinct sensitivity to the applied strain-rate, which, however, is moderate compared to the corresponding behaviour of normal concrete.
