Optimizing the compressive strength of low-grade hydrous clay …
For hydrous clay-based geopolymer (TBGM-C40), absorption bands at this peak had better transmittance than control specimen F60G40. The TBGM-C40 had better bending vibration of Al–O in AlO 4 tetrahedral and Si–O–Al than the F60G40 specimens at peaks 540 cm −1 but at 772 cm −1, TBGM-C40 had lower vibrations of the same.
