Utilization of Pechenganickel, Severonickel and Norilsk Nickel smelter plants ferrous-magnesium slag for production of Portland slag cement, lime-slag cement and alkali-activated slag cement has been considered. Influence of mechanical activation of ferrous-magnesium slag, in air and in carbon dioxide atmosphere, on its binding properties has been studied. It has been shown that preliminary mechanical activation in CO2 results in an increase of compressive strength of alkali-activated slag cement. Interaction between mechanically activated slag and liquid glass has been characterized using SEM and microprobe technique.
