Abstract: An activator composition for a non-OPC hydraulically-active material comprises CaO or lime and a polycarboxylate-ether-based (PCE) superplasticiser, and is mixable with a hydraulically active material comprising ground granulated blast furnace slag (GGBS) and/or pulverized fuel ash (PFA) to form a cementitious binder. The cementitious binder does not comprise any Portland cement and is, therefore, more environmentally friendly.
