“Shotcrete” is a wet-method for the application of special monolithic
refractory materials.

Premixed, pumpable refractory castables are conveyed to the place of
application with special high pressure pumps (approx. 250 bar) over
distances until 80 m and more.

The castables are “sprayed” with compressed air through a special nozzle.
Simultanously an accelerator is added and mixed in the nozzle, which
guarantees the bond and stability of the applicated castables at their
installation places.

Comparing with conventional refractory casting castables, the “Shotcrete”
method achieves nearly the same physical values (density, strength).

For the application no complex formworks are necessary, which saves
precious time and costs.
