And concrete pump has the feature of low pulsations for a constant concrete flow. The concrete pump is in charge of conducting the concrete mixture up to the nozzle of the spraying arm. Wet-mix shotcrete is usually pumped with double piston pumps.
The pump design is aimed at minimizing the pulsations and thus the discontinuity of the concrete flow, in order to guarantee a homogeneous application of the sprayed concrete. In this way, the required quality and layer thickness is achieved, and rebound (concrete that does not stay on the wall) is reduced.
Except the pump, there are some Shotcrete Machine commonly needed in the production like Concrete Spray Machine, Beam Bending Machine, Rust Removal Machine, Ditch Forming Machine, Curbing Machine, Canal Making Machine, Ditch Paving Machine and Concrete milling machine.
For shotcrete, there are several necessary conditions such as special shotcrete equipment, which in one way or another provides the movement of the shotcrete mix in the spray nozzle, a source of compressed air to accelerate the shotcrete mix and give it with the necessary speed for subsequent application to the surface and compaction, source of mixing water (for dry shotcrete) and trained specialist-gunman (nozzleman) or the operator of the shotcrete mix application on the surface. The shotcrete mix of a special recipe that takes into account the requirements for the properties of the shotcrete and the features of the shotcrete equipment operation.
Shotcrete is used when:
repair works: repairing concrete, reinforcement of reinforced concrete structures, elimination of construction defects, restoration of protective coating
