Gasification fly ash (GFA) generated from the municipal solid waste (MSW) slagging-gasification is strongly alkaline and has the potential to be used to activate ground granulated blast-furnace slag (GGBS) for soil stabilization. However, heavy metals like Pb and Zn in GFA would retard the hydration...
