In a general definition, hydraulic cement is a powder, that when mixed with water, undergoes a chemical reaction called hydration. The cement paste hardens and gains strength as it cures over time. Portland cement is the most common type of hydraulic cement and forms the basis of most cementitious materials used for concrete, mortar, and grout.

Before the concrete is pumped or poured, a number of simpler machines act in concert to keep the concrete from setting, and even mix the concrete at the site. Some of the older portions of the fleet, like early mixers, used paddles to stir the concrete and keep it from "settling out," or separating into its component pieces.

In the wet-process, a concrete mixture (typically ready-mix concrete) including all of the mix water is fed to the hopper of the machine, and the mixture is then pumped to the nozzle where compressed air is added to accelerate the mix onto the application surface (Fig. 4.1).Due to the reduced possibility of rebound, large aggregates (12.5 mm or larger) are often used in the mix.
