Shotcretean overview ScienceDirect Topics
Shotcrete is an "all-encompassing" term used to describe pneumatically projected concrete or mortar using either the dry-mix process or the wet-mix process. "Gunite " an old term refers only to the dry-mix process. In the dry-process (Fig. 12.1) bone dry cementitious mixture is blown to the nozzle through a hose where water is added by the nozzleman.
