In a method for dechroming and/or denickelifying liquid slags or slag mixtures, in which the liquid slag is charged onto a metal bath, in particular an iron bath, and reduced by feeding carbon or carbon carriers, the carbon feed into the metal bath is effected until a decrease of the Cr and/or Ni oxide contents of t...

In a hydraulic binder containing slags, aluminium-silicates and calcium sulphate, slag, in particular furnace slag, in amounts below 50% (w/w) as well as aluminium-silicates different from furnace slag, as for example flue-ash and natural aluminium-silicates, as for example basalt or andesite, in amounts of 5 to 75%...

A method for reducing the chromium content from a metallurgical slag, in which the slag is charged onto an iron bath in the liquid state and the reduction of Cr is effected by the iron bath having a C content of 2 to 4% by weight, wherein a) the Cr-containing slag having a Cr content of 2 to 20% by weight is charg...

In an alkali activated hydraulic binder containing slags and aluminium silicates slag, in particular furnace slag in amounts from > 20% (w/w), aluminium silicates different from furnace slag such as for example flue-ash and natural aluminium silicates, such as for example basalt, clays, marl, andesite or zeolite, in...

The invention describes a method for processing steel slagsand optionally iron carriers such as, e.g., electric furnaceslags, converter slags, dusts derived from steel production,mill scale or secondary metallurgical residues, in which themolten steel slags or iron carriers are supple...
