Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a soil stabilizer capable of hardening and solidifying high water content conhesive soil, sludge, poor ground, etc., in a sort term and moreover highly strengthening the resultant treated soil, by containing alunite-based powder, calcium sulfate-based hardener power and lime-based powder. SOLUTION: This soil stabilizer is prepared by containing (A) 100 pt.wt. alunite-based powder having a specific surface area of >=2000cm /g obtained by calcinating alunite (or its mixture with calcium carbonate and/or calcium carbonate-containing minerals) at 850 to 1200 deg.C and then milling, (B) (preferably 100 to 300 pts.wt.) calcium sulfate-based hardener powder such as natural gypsum and chemical gypsum and (C) (preferably 100 to 800 pt.wt.) lime-based powder such as calcium oxide with the quality higher than that described in JIS No.2, by-product calcium oxide-containing dust and calcium hydroxide.
