| Disclosed are a hydraulic binder composition using rapidly-cooled steelmaking reduced slag powder and a method of preparing the same. More particularly, the rapidly-cooled steelmaking reduced slag (RC-LFS) powder is obtained by spraying and scattering gas at a high pressure and high speed onto electric furnace smelting reduction slag, which is one of the by-products generated during iron smelting performed in an ironworks, and quickly cooling and pulverizing the slag. The initial high hydration heat reaction and initial setting of the rapidly-cooled steelmaking reduced slag (RC-LFS) powder are delayed to ensure workability. A retardant and gypsum are mixed into the rapidly-cooled steelmaking reduced 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 steelmaking reduced slag (RC-LFS) powder of the present invention can be used as a substitute for ordinary Portland cement. | ||||||

| For a method for granulating molten material, in particular slags, in which the molten material is introduced into a granulating chamber in which water is held as a cooling liquid, wherein the molten material is preferably quenched and granulated with evaporation of the water, an acid is added to the water. | ||||||
| 159 | METHOD FOR RECOVERING CALCIUM-CONTAINING SOLID COMPONENT FROM STEELMAKING SLAG AND RECOVERED SOLID COMPONENT | US15560711 | 2016-03-16 | US20180051357A1 | 2018-02-22 | Yasushi FUKUI; Akihiro ASABA; Shoichi MATSUO; Masaya YAMAMOTO |
| The purpose of the present invention is to provide a method for recovering calcium-containing solid components from steelmaking slag, with which it is possible to easily increase the calcium recovery rate. With the method, steelmaking slag is immersed in an aqueous solution containing carbon dioxide, and calcium in the steelmaking slag is made to leach out into the aqueous solution. Next, the immersed steelmaking slag is removed from the aqueous solution, and, subsequently, the pH of the aqueous solution is increased. When solid components precipitated by doing so are recovered, it is possible to recover solid components containing 20% or more by mass in terms of calcium atoms. | ||||||
