ABSTRACT:
Concrete is manufactured by mixing cement with substantially the exact precise quantities of water needed to produce a setting of the cement, agitating the mixture until its viscosity is substantially reduced, adding dry sand or other agrigate, mixing with a slurry, patting the mixture through a nozzle where air is introduced under a pressure and air is emitted in the form of jets into the tapering part of the nozzle, and the mixture is vibrated to achieve maximized distribution of its components while being blended and recombined during the process of gunning and feeding to the location of distribution. The concrete mix may be applied appropriately to a gun assembly or a gun type device designed dispense entrained granular materials in a compressed stream onto a work area.
