What Does Shotcrete Equipment Mean?

Shotcrete is concrete (or sometimes mortar) conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique. It is reinforced by conventional steel rods, steel mesh, and/or fibers. Shotcrete equipment allows for the projection of a concrete mixture at high pressure. Shotcrete equipment includes a mixer, an additive pump, compressor, sprayer arm and control system, and is usually found on a motorized chassis. This equipment is used in trenchless installation.


Trenchlesspedia Explains Shotcrete Equipment

The high pressure supplied by the compressor and additive pump, which accelerates the hardening process, makes the use of shotcrete highly versatile. It can be successfully sprayed vertically and upside down. The spraying arm is used to direct the flow of the shotcrete and is operated by remote control. Most equipment is designed to work with one of two kinds of concrete, wet or dry. There are some options on the market that are rated for both applications. The control system monitors the additive amount, compressor operation and collects data for later processing.
