Abstract

PURPOSE: To prevent a spraying material from clogging in a hose by a method wherein a dry mixture of cement is fed toward a spraying nozzle, and a curing accelerator powder for cement and water are mixed into the dry mixture in predetermined quantities at a position upstream of the tip of the nozzle by a distance of 40m.
CONSTITUTION: In the hose at positions away from the tip of the spraying nozzle by a distance of not more than 40m, a dry mixture containing a cement with or without aggregate is fed toward the nozzle. The dry mixture may contains a water-reducing agent for cement the main component of which is, for example, a lignin sulfonate, a β-naphthalenesulfonate-formaldehyde condensate, sulfonated melamine or the like, or other additive. After mixing the setting accelerator powder for cement into the drymixture at an arbitrary position within 40m from the tip of the nozzle, water is also mixed into the mixture and the resultant spray material is sprayed through the nozzle. Accordingly, the spray material is prevented from clogging in the hose and it becomes possible to use the setting accelerating agent for the cement poorer in accelerating effect in the setting thereof.
