REED Shotcrete Pumps and Gunite Machines
Available from REED Concrete Pumps and Gunite Machines
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.
