The present invention is a technique for high value-added utilization of the reduced slag of electricity that has been discarded because it has a high content of free lime (free-CaO), which has not been utilized in the past. More specifically, the present invention is an ultra-fast-hard hydraulic binder prepared by mixing reduced slag powder, which is pulverized by quenching at room temperature by scattering reducing slag with electricity of high pressure gas among by-products generated during iron smelting at an ironworks, and gypsum. The present invention relates to a manufacturing method, which can be used in various fields requiring fast hardening properties, and by using coagulation with gypsum to adjust the setting and curing time. It relates to a super-speed hard hydraulic binder and a method of manufacturing the same. |
