Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a disintegrable material which has a given strength and shape when heated to a target temperature and which becomes disintegrable after the subsequent lapse of a given time period. SOLUTION: The disintegrable material is characterized by comprising a base made of a hydrate of a hydraulic material and unexpanded vermiculite particles dispersed in the base. The hydraulic material preferably comprises at least one of cement and gypsum and the unexpanded vermiculite particles are preferably contained in an amount of 0.5-15 wt.%. In addition, the disintegrable material preferably contains Shirasu balloons in an amount of 0.5-20 wt.%. Further, it is preferable that the surface of the base has, formed thereon, a coating film constituted of a hydrate of a hydraulic material and a silica powder. COPYRIGHT: (C)2009,JPO&INPIT
