PROBLEM TO BE SOLVED: To provide a soil solidification composition excellent in soil solidification property, good in safety and biodegradability, without being eluted even with contacting with water such as rain nor risk of salt damage.SOLUTION: The invention provides a soil solidification composition containing (A) component: carboxymethyl cellulose or a salt thereof, (B) component: a cationic polymer, and (C) component: at least one kind of salt selected from a group consisting of sulphate, phosphate, and nitrate, and a solidification method of soil by spraying the composition to the soil. The (A) component preferably has DS of 0.4 to 1.1 and 1% viscosity of 300 to 2000 mPa s, the (B) component preferably has cationization degree of 3.8 to 4.2 meq/g and molecular weight of 3,000,000 to 7,500,000, and is polyacrylic acid ester-based compound or polymethacrylic acid ester-based compound, and the (C) component preferably contains an ammonium salt such as ammonium sulphate, ammonium nitrate, and ammonium phosphate.SELECTED DRAWING: None |
