摘要

PROBLEM TO BE SOLVED: To provide a blast furnace slow cooling slag roadbed material capable of inhibiting generation of expansive sulfate hydrate without modifying blast furnace slow cooling slag using large-scale facilities for desulfurization, controlled cooling from high temperature, and the like, without adding expensive reagents, and without impairing strength, and to provide a method for manufacturing a blast furnace slow cooling slag roadbed material and a method for constructing a blast furnace slow cooling slag roadbed material.SOLUTION: In a blast furnace slow cooling slag roadbed material according to the present invention, one or two or more additive materials containing at least one of water-soluble silica, water-soluble iron and a water-soluble magnesium are mixed into blast furnace slow cooling slag.SELECTED DRAWING: None
