SOIL SOLIDIFICATION COMPOSITION
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
【課題】本発明の目的は、土壌固化性に優れ、安全性及び生分解性が良好であり、雨など水と接触しても溶出することがなく、塩害のおそれもない土壌固化組成物を提供することである。【解決手段】本発明は、（Ａ）成分：カルボキシメチルセルロース又はその塩、（Ｂ）成分：カチオン性高分子及び（Ｃ）成分：硫酸塩、リン酸塩、及び硝酸塩からなる群より選ばれる少なくとも１種類の塩を含有する土壌固化組成物、及び該組成物を土壌に散布する土壌の固化方法を提供する。（Ａ）成分は、ＤＳが０．４〜１．１、１％粘度が３００〜２０００ｍＰａ・ｓであることが好ましく、（Ｂ）成分は、カチオン化度が３．８〜４．２ｍｅｑ／ｇ、分子量３００万〜７５０万、ポリアクリル酸エステル系化合物又はポリメタクリル酸エステル系化合物であることが好ましく、（Ｃ）成分は、硫酸アンモニウム、硝酸アンモニウム及びリン酸アンモニウム等のアンモニウム塩を含むことが好ましい。【選択図】なし
