To obtain a spraying material, free from the clogging of a nozzle and the loss of the function of an accelerating agent, and capable of improving the strength generation in the initial and intermediate periods and after a long time and reducing a rebounding ratio.
This spraying material is obtained by compounding a cement mortal mainly consisting of a fluorocalciumaluminate-containing cement and gypsum with an accelerating agent mainly consisting of calciumalminate directly before spraying. Preferably, the cement mortal is compounded with at least one kind selected from a water-reducing agent, a setting retarder, a setting accelerator and ultrafine powder, and the accelerating agent is compounded with alkali aluminate and/or alkali carbonate. Further, an accelerating agent mainly consisting of calciumaluminate is joined to a cement mortal mainly consisting of a fluorocalciumalminate-containing cement and gypsum just before spraying and they are directly sprayed.
