PROBLEM TO BE SOLVED: To provide an expansion inhibitor for fly ash capable of effectively inhibiting the expansion of fly ash having a high free lime content, to provide a hydraulic composition containing the same, to provide a fly ash hardened body using the same and to provide its production method.;SOLUTION: The expansion inhibitor for fly ash contains mineral acid. The hydraulic composition, e.g., contains: fly ash having a free lime content of ≥2%; a stimulant; and the expansion inhibitor for fly ash. The fly ash hardened body is produced using the hydraulic composition. In the method for producing the fly ash hardened body, the hydraulic composition is kneaded with water, and it is packed into a molding flask while being subjected vibration compacting, so as to be molded.;COPYRIGHT: (C)2006,JPO&NCIPI
