What is gunite?

There are two main things that differentiate gunite from concrete. Firstly, unlike concrete, which uses large and small aggregates, gunite only uses small particles. The other difference is down to when you add the water. As we stated earlier, concrete comes ready mixed. With gunite, on the other hand, a dry mix is fired through a hose with the water being added at the point of delivery.

"Gunite" defined

Often regarded as the authority on all matters of shotcrete, the American Shotcrete Association (ASA) defines "gunite" as "dry-mix shotcrete." Although this hasn't really caught on in the gunite industry, "dry-mix" is a term that is used in more technical shotcrete circles, by high profile, often multi-national, companies who perform critical shotcrete repair projects on tunnels, bridges, columns, underwater and other projects of that high caliber. But for the typical gunite crew in the USA, gunite is still "gunite", period. In any case the ASA defines dry-mix shotcrete, aka "gunite" as the following:

"Pre-blended dry or damp materials are placed into the delivery equipment. Compressed air conveys material through a hose at high velocity to the nozzle, where water is added. Material is consolidated on the receiving surface by the high-impact velocity."

Gunite Description #76

As the water meets the dry material at the gunite nozzle, the nozzle man safely and skillfully must direct the high velocity sprayed material distributing it onto the #swimmingpool construction shell. The resulting wet material is akin to concrete, although it does not contain any large aggregates/rocks. The material is better described as mortar or even "gunite" because the word gunite is used to refer to the complete process just described but it is also used as a name for the material itself.
