The invention relates to a cement composition which can be hardened hydraulically and which consists of ground cement clinker material, granulated blast furnace slags and comminuted steel slags. The comminution of the steel slags is preferably carried out by grinding, in particular to a particle size of at most 0.2 mm and expediently to 0.09 mm. The ground steel slags have a Blaine value of at least 400 m²/kg, expediently 473 m²/kg, and a weight per unit volume of 2,800-4,000 kg/m³. The steel slags are chosen from air-cooled steel slags, foamed steel slags, granulated steel slags or a combination thereof. A method is also described for the preparation of a cement composition which can be hardened hydraulically, in which method cement clinker material and ground, granulated blast furnace slags are mixed with ground steel slags at normal or elevated temperature and pressure, the obtained mixture is cooled if desired, and comminuted to obtain a hydraulically hardenable cement composition. Use is made of a cement furnace if the present cement composition is prepared at an elevated temperature. Preferably a mixture of blast furnace slag cement and ground steel slags containing up to 30% of steel slags, or a mixture of Portland cement and ground steel slags containing up to 50% of steel slags is formed. |

Die Erfindung betrifft ein Verfahren zur Aufbereitung von Stahlwerkschlacken zum Herstellen eines hydraulischen mineralischen Bindemittels mit hohem Erhärtungspotential und zum Rückgewinnen von Eisen. Hierzu ist es vorgesehen, ein Aufgabeprodukt bereitzustellen, welches Stahlwerkschlacke mit MnO aufweist. Dieses Aufgabeprodukt wird als Schmelze weiterverarbeitet, indem Reduktionsmittel in die Schmelze eingebracht werden. Hierbei soll im mineralischen Schmelzanteil ein Kalkstandard zwischen 90 und 110 erreicht werden. Anschließend wird die Schmelze definiert abgekühlt und elementares Eisen aus der erstarrten Schmelze mechanisch abgetrennt. Dann wird die erstarrte Schmelze einer Verwendung als hydraulisches mineralisches Bindemittel zugeführt. |
