eng Photonic Doppler Velocimetry instrumentation in real scale concrete slab blast loading experiments with an attempt to measure the influence of the type of concrete on the debris velocity The author team has performed a set of experiments in the past years focused on blast performance of concrete slabs subjected to adjacent blast loading. The 2014 tests focused on blast performance of slabs with 40 or 80 kg/m3 of steel fibers; the fibers were high strength, fy=2000MPa. The slabs made of UHPFRC were tested. The response of the soffit of the slabs was recorded by high speed cameras. The crack propagation is put in correlation with the results of numerical modelling. The velocity of the debris at the soffit of the slabs under the blast loading was recorded using PDV. blast loading; concrete; photonic Doppler velocimetry; high speed camera
