Abstract : The analysis of the chemical composition, functional groups, and crystalline phases of carbon steel slag was conducted using X-ray fluorescence spectroscopy (XRF), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The analysis helps in predicting the reaction that might occur during the alkalization, dissolution, and polymerization to form a geopolymer chain. Therefore, the presence of Si-O-Si, Si-O-Al, and Fe-O functional groups in the raw materials will most likely contribute to the reaction. Furthermore, the high amount of Si, Al, Fe, and Ca can contribute to the geopolymerization potential. Moreover, the XRD analysis shows that the China clay mainly consists of kaolinite. Carbon steel slag shows larnite, hematite, mullite, and gehlenite phases. This study suggests opportunities for future research on carbon steel slag incorporated in geopolymer ceramic.
