Beschreibung
Zusammenfassung:	Agglomerated stone comprising (wt.%):cement binding agent (6-15), carbon carrier (up to 20), residual and recyclable substances (up to 20), and optionally accelerator (up to 10), remainder iron ore stone in the form of particles of grain size below 3 mm. After 3 days the iron ore has an initial strength of at least 5 N/mm2> and after 28 days a cold compression strength of at least 20 N/mm2>. An independent claim is included for a method of preparing the stone as described above by transfer of the composition to a mold and compacting.
