Blast performance of FRC specimens with steel fibers of low ductility

Popis výsledku v původním jazyce

Abstract: Due to improved ductility, fibre-reinforced concrete (FRC) shows better performance under blast and impact loading compared to conventionally reinforced concrete. Also higher concrete strength shows better blast performance. The full scale blast tests of FRC and reinforced concrete specimens were performed in cooperation with the Czech Army corps in the military training area Boletice. The tests were performed using real scale reinforced concrete precast slabs (6x1.5x0.3m) with varying fiber content, fiber type, fiber strength and concrete strength class and 25 kg of TNT charges placed in distance from the slab for better simulation of real in-situ conditions. The paper presents conclusions from three sets of tests from years 2010, 2011 and 2013: eleven specimens were tested in total. Two specimens of different concrete strength were tested as reinforced concrete specimens to provide comparison to the nine FRC specimens of different fiber content (0.5% and 1%): polypropylen f
