Zusammenfassung:	PROBLEM TO BE SOLVED: To efficiently cure and solidify a calcium silicate-based building material for a short time. SOLUTION: A mixed raw material comprises a silicic raw material, a calcareous raw material, a reinforcing fiber and water and contains an alkali hydroxide in an amount of 4 pts.wt. or below as a solid component with respect to 100 pts.wt. of the total amount of the raw material mixture solid content. This mixed raw material is molded and the molded body is pre-dried at a predetermined temperature to be cured and solidified under atmospheric pressure in a steam atmosphere while adjusting the irradiation output of microwave pulses and the on/off time of the irradiation output. The cured and solidified body is subjected to post-drying to obtain a ceramic molded object. COPYRIGHT: (C)2005,JPO&NCIPI
