Granulated iron silicate slag, a by-product of pyrometallurgical copper extraction, has excellent properties for construction applications. Slag modification with CaO enhances the application regarding pozzolanic reactivity, potentially extending slag use in future. The slags’ short-term leaching behavior already been investigated promising results, while long-term effects are less studied. The...

Glass-ceramics (GCs) are materials obtained from the crystallisation of functional phases in glass, and have a structure that the crystallised phase embedded in the glass matrix. Glass-forming oxides are commonly added to the functional phases to improve the stability of precursor glass; however, the issue of glass-ceramics permitting the presence of residual phases resulting from addition is r...

Copper in discarded slag decreases the profits and copper recovery during pyrometallurgical extraction processes. The losses to can be reduced by using a settling furnace, which mechanically entrained droplets separate from under action of gravity. rate increased modifying composition and, thus, properties, are known influence rate. knowledge industrial CaO modification iron silicate with Fe/Si...

Traditional methods to track the reactivity of supplementary cementitious materials (SCMs) and their contribution hydration mechanism mostly use Portland Cement (PC) as an activator. Alternatively, a novel method assess SCMs called R3 was recently presented. This uses lab grade chemicals such portlandite (CH), K2SO4, KOH, CaCO3 activate SCM by resembling pH alkaline pore solution created PC. By...
