ABSTRACT

The brief survey of basic research of rock and concrete disintegration by water and abrasive jets in the area of physical of jet-abrasive interaction, mathematical modelling of several aspects of high pressure water and abrasive jet, the measurement of the non-setting parameters of the high pressure water jets, high pressure abrasive jet cutting using linear stepping movement, liquid flow from nozzle and experimental study of discharge coefficient and application of high-pressure waterjet technology in a construction company s practice noted.
