(57) [Summary] [Problem] Immediately after spraying, rapid hardening cement concrete can be prevented from sagging, falling from slopes, leveling iron, and overspraying. A slope spraying material with excellent aesthetics is obtained, strength development and pumpability are improved, work time can be reduced, the burden on workers is reduced, and slope spraying with good workability can be performed. Hardener, To provide hardened cement concrete and its spraying method. SOLUTION: A hardening cement for spraying comprising a hardening substance and an acrylic ester copolymer emulsion, a cement, the hardening agent, a water reducing agent, an inorganic powder, and a hardening cement containing a fiber. The rapid hardening cement concrete is sprayed on concrete and a frame skeleton to form a slope spraying method for constructing a frame. |
