Abstract

PURPOSE: To avert trouble of closing and to make changing of mix proportions corresponding to conditions possible by air feeding cement and a mix proportion excluding cement through separate systems, mixing these in the air flow just before a spraying nozzle and spraying the mixture onto the work surface.
CONSTITUTION: A mix proportion A consisting of aggregate, admixture or a constant amt. of water excluding cement is fed out continuously at a constant rate by means of a rotor 8 having a pocket 9 from a containing part 6, and is air fed to a conveying hose 3 by the compressed air from air blowing parts 7, 7'. Cement powder B is fed continuously at a constant rate from a container 15 into a hose 18 through a discharge part 16 by a constant volume dispensing mechanism 21 and an air blowing part 17, and through a conduit port 13, it enters the hose 3, where it is mixed vigorously with the mix proportion A to the form of paste during conveyance. This cement admixture is added, if necessary, with a constant volume of water in a water adding part 5, and is sprayed from a spray nozzle 4.
