Fly ash based alkali activated material and geopolymer were synthesized at 80°C and the reaction products in each hardened paste were investigated. 29Si-NMR, 27Al-NMR and FT-IR were obtained to discuss the network structure of the amorphous phase. SEM-EDX was measured to understand the element composition. It was suggested that the hardened paste with a large proportion of Na element inhibited the network formation of Si-O-Si or Si-O-Al, and thus the amorphous phase having a low dimensional network structure increased.
