Abstract

Gegenstand der Erfindung ist ein aus Schlacken gewonnener Zuschlag- und/oder Füllstoff, ein Verfahren zu seiner Herstellung und seine Verwendung. Erfindungsgemäss wird ein aus Metall- oder Eisenhüttenschlacken gewonnenes Recyclat mit weniger als 1 Gew.-% freies CaO bzw. weniger als 1 Gew.-% Nitride (für Aluminiumhüttenschlacken) bereitgestellt. Das Verfahren zur Herstellung des Recyclats umfasst im Wesentlichen die Umsetzung von Metallhüttenschlacken mit eisensulfathaltigen Additiven.
