The extracted titanium tailings slag (TS) is a byproduct of titanium extraction from the blast furnace slag. Its chemical composition is similar to that of ground granulated blast furnace slag (GGBS), but the relatively lower reactivity limited its utilization as a supplementary cementitious material. In this study, the reactivity of TS was improved by mechanical grinding, and the optimum ...

Introduction. Granulated blast furnace slag (abbreviated GBFS) is an industrial solid waste generated in the steelmaking process [1], [2]. It is rich in CaO, SiO 2, Al 2 O 3 in chemical compositions and the mineral phases of GBFS are mainly composed of glass phases [3], [4]. Based on its chemical and mineral compositions, GBFS has a good hydration activity [5], [6], [7], [8].
