It is a dry-mix shotcrete machine which is also known as gunite machine. This model of dry mix shotcrete machine is successfully used in applications at dam, subway, railway, super highway constructions; in engineering, underground engineering as well as tunneling and mining operations, and in hydropower projects, slope stabilization, shaft chamotte plaster work, and repair and restoration.
Shotcrete process requires compressed air to convey the pre-dampened mix through delivery hose to the nozzle to project the material onto the surface. Under high velocity, concrete support layer is formed after the projected material coagulates and hardens.
After its connection to an extra site air compressor, it successfully projects the shotcrete material onto the surface it is applied to.
