摘要

A method of treatment of steelmaking-slag for stabilization characterized by adjusting the steelmaking-slag to an amount of moisture or amount of carbonated-water of a range less than the moisture value where free-water starts to be present and at least a value 10 mass% smaller than that moisture value, then supplying a flow of CO 2 gas for carbonation treatment without allowing the grains of the steelmaking-slag to bind with each other. The steelmaking-slag treated for stabilization can be used for a civil engineering material or water environment protection material.
