PROBLEM TO BE SOLVED: To set a long initial time and a long-term strength by reacting rapidly after a predetermined time by mixing each of the slurries before mixing, and hence the pot life is long. In addition, the present invention provides an inorganic ground injecting material that exhibits high performance and has high permeability into the ground, and can firmly stabilize the entire target ground. An aqueous slurry (I) containing (A) calcium aluminate, (B) gypsum, (C) a setting retarder, (D) a hydraulic inorganic substance and (E) a set retarder A ground injection material obtained by mixing aqueous slurry (II).
