Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for fluidization wherein a solidifier having an ettringite precursor and a fluidizer or a water reducing agent are used, and whereby the soil of excavation at the site of field can be utilized as such, the flowability can be sufficiently ensured, and a suitable strength can develop in a specified time. SOLUTION: In a work for fluidization comprising fluidizing soil of excavation by mixing with water, adding a solidifier having an ettringite precursor (e.g. a cemental solidifier based on calcium sulfoaluminate) to the mixture and refilling with the formed product, the solidifier is first added to the mixture, and the fluidizer or the water reducing agent is then added to the resulting mixture. According to this process, soil of excavation produced at the site of a field can be used in the state in which it has sufficient flowability, develops suitable strength in a specified time and is not excessively soft or hard.
