PROBLEM TO BE SOLVED: To provide a solidifier capable of stabilizing a soil in a neutral region without an alkaline region, and capable of preventing fluorine in the soil from being eluted; and to provide a method for improving the solidification of the soil by using such the solidifier. SOLUTION: The solidifier for improving the solidification of soft soil contains anhydrous gypsum and hemihydrate gypsum regulated so that the value of (the content of the anhydrous gypsum)/(the content of the hemihydrate gypsum) is≥0.2 and≤0.6, and the content of the anhydrous gypsum based on the whole solidifier is≥15 wt.%. The method for improving the solidification of the soil involves blending the solidifier in a proportion of≥30 kg/m<SP>3</SP>and≤300 kg/m<SP>3</SP>with the target soil.
