With "wet-process shotcrete" a low-slump concrete
mix is pumped with a Concrete
Pump to the end of the pipeline where a special
"shotcrete nozzle"
is attached. That shotcrete nozzle introduces compressed
air to the concrete. This compressed air typically
comes from a 165-185cfm air compressor - sold separately.
The addition of the compressed air adds velocity
to the concrete so it sprays out of the nozzle.
This velocity, combined with the low slump of the
shotcrete mix, allows the concrete to be sprayed
on slopes, vertical walls, and overhead.
Gunite, also
known as "dry process shotcrete", uses
a different process than the concrete
pumps listed above. Gunite machines use
air pressure to convey dry material from the machine through the hose
to the nozzle where water is added.
