PROBLEM TO BE SOLVED: To provide a method for treating a slag-mixed soil, capable of enhancing kneadability of a cement being an insolubilizer with the slag-mixed soil, and capable of reducing the addition amount of cement for satisfying the elution standard of fluorine as much as possible.SOLUTION: The method for treating the slag-mixed soil includes charging the slag-nixed soil M containing fluorine in a crushing/mixing unit 10 while adding cement as an insolubilizer to crush into fine particles, and mixing with cement. For details, a rotary crushing/mixing device is used in which the multistage impact chains 13 rotating inside a cylindrical casing 11 are arranged. The method includes charging the slag-mixed soil in the cylindrical casing while adding cement as the insolubilizer, crushing the soil to the level of a fine particle-mixed rudaceous sand in a soil classification by the striking force of multistage impact chains rotating in the cylindrical casing, and then mixing with cement. |
