PROBLEM TO BE SOLVED: To provide a grouting material coping with the practice and schedule of construction work, exhibiting a stable slurry state resistant to the change of fluidity even by leaving in a kneaded state before mixing a slurry containing a quick hardening agent with a cement suspension, free from abrupt change of the gelling time from a preset time in the case of mixing a kneaded slurry in use and having good strength developing property. SOLUTION: The grouting material is produced by mixing a slurry A containing a gypsum mixture composed of gypsum anhydride and gypsum dihydrate at an (anhydride/dihydrate) weight ratio of 50/50 to 85/15 with a slurry B containing cement.
