PROBLEM TO BE SOLVED: To provide a method for manufacture of a high quality dehydrating- press-molded body which is excellent in bending strength and toughness. SOLUTION: The method for manufacturing the dehydrating-press-molded body comprises the steps of molding a composition containing hydraulic inorganic material, a crystalline inorganic filler 10 μm to 2 mm in average particle size, noncrystalline silica 0.01 to 1 μm in average particle size and a synthetic fiber by dehydrating pressing and then hardening the molded body by curing. The temperature of the composition at start of molding is set at 25 to 45 deg.C. Therefore, leakage from a form is not generated in pressing, and the dehydrating press molded body can be easily obtained. |
