1. A system for applying a construction material, the system comprising:
a first source of a first component that is a pumpable building material;
a second source of a second component that is a pumpable substance which includes at least one of an accelerating admixture and a hardening accelerator; and
a moving device having at least a movable portion and a mixer that is arranged on the movable portion,
wherein the mixer comprises:
a drum having at least one inlet and at least one outlet, the system being configured so that the first source and the second source are in fluid communication with the at least one inlet so that the first component and the second component being are fed to the mixer via the at least one inlet,
a drive,
a stirring shaft configured to receive the first component and the second component from the at least one inlet and mix the first component and the second component to produce the construction material, the stirring shaft being arranged in the drum and being coupled to the drive, and
a conveying device arranged in the drum, the conveying device being arranged on an axis of the stirring shaft and configured to convey the construction material toward and through the at least one outlet,
wherein the moving device is configured to move the mixer of the moving device independently in three dimensions to apply the construction material and to construct a structure from the construction material.
