PROBLEM TO BE SOLVED: To provide a spray method for a fiber-reinforced material that does not require a quick setting agent.SOLUTION: In a spray method for a fiber-reinforced material of the present invention, the following steps are performed: first, fresh mortar is prepared by blending cement, silica fume, water, a water-reducing agent, and sand that is a fine aggregate, such that a blended amount of the cement and the silica fume is between 1,000 and 1,100 kg/m, a blended amount of water is between 245 and 266 kg/m, and a blended amount of sand is between 931 and 958 kg/m, or by ratios shown in Table 1 for example, and mixing the blended ingredients with an agitation mixer (101); then, fiber-reinforced mortar is prepared as a fiber-reinforced material by adding a vinylon fiber as a fiber to the fresh mortar at blended amounts shown in Table 1, and mixing further (102); and the fiber-reinforced mortar is sprayed on a portion to be sprayed (step 103).SELECTED DRAWING: Figure 1 |
