| Description
| - According to recent publications, from 2005 to 2008 there were more than 13000 terrorist attacks around the world, which took more than 73000 human lives. The attacks were targeted mainly on the technical and civic infrastructure, like governmental buildings, bridges, etc. 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. Field tests of FRC and reinforced concrete specimens were performed in coopera tion with the Czech Army corps in the military training area Boletice. The test 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 were without fibers and had different concrete strength. Polypropylen fibers with length 54mm and strength of 600MPa and steel fibers with low ductility 25mm long and strength 400MPa were added in different content (0,5% and 1%) to the other nine specimens.
