PROBLEM TO BE SOLVED: To obtain a composition, which comprises, as its essential components, specified amounts of a slug, aluminium sulfate and/or iron sulfate and a lithium salt, and the balance alumina cement, thereby improving the solidification-improving property of moisture-containing soil.;SOLUTION: The amount of a slug in the solidifying material ranges 10 to 50 pts.wt. per 100 pts.wt. of the essential components, that of aluminium sulfate and/or iron sulfate ranges 10 to 30 pts.wt. per 100 pts.wt. of the essential components, and the amount of the lithium salt ranges 2.5 pts.wt. to 5 pts.wt. per 100 pts.wt. of the essential components. The most preferred lithium salt is lithium carbonate. The solidifying material may further comprise an inorganic porous moisture-absorbing material and/or an organic polymer moisture-absorbing material, so that the uniaxial compression strength of the soil obtained after improvement in solidification can further be improved, with the soil after the addition of the solidifying material suffering little variation in the pH value. The inorganic porous moisture-absorbing material preferably includes perlite or the like, and the organic polymer moisture-absorbing material preferably includes synthetic polymers such as polyacrylamide or the like, or a natural material such as waste paper or the like.;COPYRIGHT: (C)2000,JPO
