What is Guniting? Procedure, Applications and Advantages
The application is facilitated by the addition of water at the nozzle area. The mix that finally comes out is a combination of dry material and water. The operator has the control on the addition of water and the combination water content. The mix used in guniting is cement mortar mix.
Dry mix process and wet mix process are the two methods of shotcrete construction which are based on the time at which the water is added to the mortar or Shotcrete is a type of concrete or mortar mix that is shot onto a surface at high-speed. The shotcrete process can be performed in two ways, either using a dry mix or by means of a wet mix.

How to Calculate Quantities of Cement, Sand and Aggregate for Nominal Concrete Mix
The dry volume of concrete mixture is always greater than the wet volume. The ratio of dry volume to the wet volume of concrete is 1.54. So 1.54 Cum of dry materials (cement, sand and aggregate) is required to produce 1 Cum of concrete. Volume of Cement …
An Introduction to Dry Cast Concrete| Concrete Construction
Wet troweling is unnecessary, and special architectural effects and finishes can be worked into the dry material at little cost by means of hand tools, shaped screeds or rollers having patterned surfaces. The resulting concrete is virtually free of air bubbles and honeycombing, and the surfaces are characterized by exceptional form definition.
