Hugoniot properties for concrete determined by full-scale detonation experiments and flyer-plate-impact tests

摘要

Two different and independent shock compression experiments have been performed in order to determine equation of state (EoS, Hugoniot) properties of concrete. The techniques used in the present study are full-scale detonation experiments where pressures were obtained in the affected concrete body with carbon resistor gauges, and, flyer-plate-impact tests where subsequent velocity histories were monitored by a VISAR (velocity interferometer system for any reflector) and the related pressures and densities evaluated by means of the conservation equations. The different specimens have been produced with concrete out of the same charge. The experiments were performed in different laboratory locations but at the same time. Pressure-density data are reported from both methods up to 16 GPa. The investigation has been carried out in order to assess the validity of two different methods with respect to EoS-data. To the knowledge of the authors, this has not been done before.
