Zusammenfassung:	A spray nozzle for shotcreting comprising a first member (3), a second member (7) releasably connected to the first member (3), and a nozzle head (12) slidably located in a bore in the second member (7). Dry concrete mix is conducted to the nozzle head (12) via the first member (3) while water is led to openings (17) in the nozzle head (12) via a chamber (9) in the second member (7). The openings (17) are arranged in axially spaced series whereby axial movement of the nozzle head (12) adjusts the number of openings within the water chamber (9).
