Abstract (in english)
   The concrete samples with various erosion states were disintegrated inside the overpressure vessel using high-velocity water jet and depth of penetration was measured. Removing of the eroded parts of samples was also tested using low-pressure generated continuous or pulsing fan jets and rotating jets. The influence of the erosion states, water jet techniques, traverse rate and stand-off distance on the disintegration volume was studied and the surface topography was investigated. The high-pressure generated continuous water jet was applied in the overpressure vessel used for simulation of pressures equivalent to the submersion to several depths under the water level. The low-pressure generated continuous or pulsing jets were applied in air conditions. Some samples of special decorative concretes were also studied.
