PROBLEM TO BE SOLVED: To provide a method for producing inorganic hardened body which delays a reaction of cement as necessary and, on the other hand, performs sufficient hardening on the final process. SOLUTION: In this producing method, fiber and cement are used as main material, slurry is made by dispersing a material including the main material with water, a product form is made by performing dewatering and forming and, thereafter, is hardened by aging and an inorganic hardened body comprising fiber reinforced cement is thus produced. A delaying agent is added to the slurry by a prescribed amount and, after wet heat aging, the autoclaving of >=130 deg. and >=2 hr is performed. |
