Table 2 shows the mix proportions of geopolymer concrete (GC)
in this study. Liquid to ash ratio (L/A) of 0.6 and NS to NH ratio of 1.5
by weight were used for all mixes. Fly ash and NH solution were
mixed for 5 min and then coarse aggregate and fine aggregate in
saturated surface dry condition were added and mixed for another
5 min, and finally NS solution was added and again mixed for 5 min.
