The present invention relates to a quick-setting concrete containing a rapid-reducing steel slag powder, and more particularly to a rapid-setting concrete comprising a powdery quench steel reduction slag powder added to cement for accelerating the rapid hardening- Wherein the rapid setting is such that the high-pressure and high-velocity gas are sprayed and scattered in the electric furnace melted reducing slag during the iron smelting in the steel mill for 5 to 60 seconds to disperse the molten reduced slag at 1,300 to 1,600 ° C at 40 to 90 ° C And a rapid-cooling steelmaking reducing slag powder consisting of a mixture of a rapidly quenched steel-making slag powder pulverized by a powder of 3,000 to 12,000 cm2 / g and a mixture of sodium carbonate, gypsum, slaked lime, sodium aluminate and a thickener, . |
