  Self-compacting geopolymer concrete (SCGC) is an advanced concrete that reduces both vibration and usage of cement. In this study, SCGC mixes were carried out with 50:50 proportions using class F fly ash (FA) and ground granulated blast furnace slag (GGBS) with artificial sand (ARS) as fine aggregate. By following EFNARC guidelines and carrying out trial mixes an optimum proportion is used for 8M, 10M and 12 M of NaOH. The present research is mainly concentrated on fresh properties of SCGC by varying the molarity of sodium hydroxide (NaOH) with 8M, 10M and 12M. The test methods such as Slump flow, T50cmslump flow, V-funnel and L-box were conducted. Studies also exposed that the fresh properties were decreased when the NaOH molarity was increased.
