<p>The invention concerns a method for the production of pozzolanic or hydrauli c binders for the cement industry from basic oxidic slags, especially steel slags, using a metal bath for reducing metal oxides in the slags. According to said method, the basicity of the liquid slags is adjusted, prior to reductio n, to a value that is 0.1 to 0.5 lower than the basicity value (Ca0/Si02) of th e target slag by adding acid correction materials such as silica sand and/or blast furnace slag and/or correction materials containing SiO2.</p> |
