Super-fast hardened hydraulic binder using reduced slag powder and method for producing the same

摘要

Provided are an ultra-rapid hardening hydraulic binder including reduced slag powder and a method of preparing the same. The reduced slag powder is prepared by rapidly cooling molten electric arc furnace reduced slag, among by-products generated during an iron refinement process in a steel mill, to room temperature not to have free-calcium oxide by scattering the molten electric arc furnace reduced slag into the air using high-pressure gas by dropping the molten electric arc furnace reduced slag through a tundish.
