Abstract (in english)
   The paper is dealing with effects of flat high-speed water jet on concretes affected by high temperature. Several concrete mixtures were prepared for tests of interaction of water jet with concrete samples: 1)unaffected by high temperature, 2)exposed to 200°C and 3)exposed to 600°C- Achieved results are analyzed and discussed. Research should help especially after wildfires in tunnels, underground garages, etc., which are exposed to enormous thermal stress.
