Steel slag multi-phased clinker is a cement clinker directly calcined by granular steel slag, so the physical and chemical characteristics of steel slag are very important to the sintering of multi-phased clinker. In order to explore the influence mechanism of different types of converter steel slag on the sintering and properties of multi-phased clinker, three kinds of multi-phased clinker were prepared by using hot smoldering slag, roller slag and pressurized hot smoldering slag at 1 420 ℃. The results show that the multi-phased clinker minerals with different steel slag were mainly C3S, C2S and C4AF, the higher iron content in steel slag resulted in the Al transformed into ferrite minerals, showing a typical high ferrite (Ferrite content > 18%, mass fraction) characteristic. The differences of chemical composition, mineral composition and particle size distribution among different steel slag had different influences on the formation and development of mineral crystals and properties of multi-phased clinker. The content of water-soluble chromium (VI) in multi-phased clinker was positively correlated with the content of Cr2O3 and alkali in steel slag, and the higher the content of fine particles in steel slag, the more easily Cr was oxidized into water-soluble high valence chromate in the sintering process.
