ABSTRACT:
A treatment method includes injecting oxygen into the liquid steel works slag, adding and dissolving in the slag alumina and lime sources, and optionally silica and iron sources and cooling the slag until solidification, the additions being carried out in such amounts and the cooling being performed at such speed that the resulting slag has a mineralogical composition having one of the following constituting element: (a) an amorphous glassy phase; (b) a first group of phases (1) consisting, in weight percentages, of 10–40 CA, 20–50 C2AS, 30–50 C6AF2 and 10–30 C2S; (c) a second group of phases (2) consisting, in weight percentages, of 20–40 C2F, 10–30 C2AS, 20–50 C6AF2 and 10–40 C2S, and (d) a mixture of amorphous glassy phase and of the first or second group of phases. The invention is applicable to hydraulic binders.
