The method based on the generation of acoustic waves by the action of the acoustic transducer on the pressure liquid and their transmission via pressure system to the nozzle was used for generation of pulsating jet for removal of concrete layers in laboratory conditions. A series of laboratory experiments was performed to compare effects of pulsating and continuous flat jets acting on concrete blocks exposed to various corroding medium. Obtained results are discussed in the paper.
