The present invention relates to a hydraulic binder composition using rapidly-cooled ladle furnace slag powder and to a method for preparing same. More particularly, the rapidly-cooled ladle furnace slag (RC-LFS) powder is obtained by spraying and scattering gas at a high pressure and high speed onto the electric arc furnace reducing slag, which is one of the by-products generated during iron smelting performed in ironworks, and quickly cooling and pulverizing the slag. The initial high hydrothermal reaction and initial setting of the rapidly-cooled ladle furnace slag (RC-LFS) powder are delayed to ensure workability. A retardant and gypsum are mixed into the rapidly-cooled ladle furnace slag (RC-LFS) powder so as to activate the generation of needle-shaped ettringite and to thus develop the initial and long-term strength, and therefore the rapidly-cooled ladle furnace slag (RC-LFS) powder of the present invention can be used as a substitute for ordinary Portland cement.
