PROBLEM TO BE SOLVED: To prevent the generation of crease, blister and efflorescence caused by the dew condensation on the surface of a molded article in the thermally accelerated curing of a molded article produced by the dehydrating compression molding of a hydraulic composition and further prevent the lowering of strength by dew condensation and drying. SOLUTION: A molded article produced by the dehydrating compression molding of a hydraulic composition is placed in a closed space essentially free from the transfer of water vapor to the outer environment and the closed space is heated from the outside of the space to effect the thermally accelerated curing of the molded article. The dew condensation and the drying of the surface of the molded article can be prevented by the placement of the molded article in the closed space. |
