“…Past research on geopolymer had centered on the use of alkali-activated fly ash and slag as binder [3,16,17,18], investigation of non-calcined natural kaolin as partial replacement of cement [19,20,21,22]. Also, study on development of geopolymer concrete using ground granulated blast furnace slag [23,24,25] and palm oil fuel ash-fly ash [26,27,28,29,30,31,32]. Thus, this research will provide a sound platform which will reveal the full potential of the developed GPC as novel concrete that can provide enhanced strength and durability at different curing temperatures.…”
