Abstract

ABSTRACT: Geopolymer materials are progressively studied due to their good properties that can even be compared to Portland cement concrete. For geopolymerization, a precursor material is required, which is rich in alumina (Al2O3) and silica (SiO2). Ladle furnace slag is an industrial waste that suits the needs of geopolymer synthesis. This study analyzes the geopolymerization performed with ladle furnace slag through X-ray diffraction (XRD); Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) analyses. With the XRD analysis, it was possible to identify crystalline phases and some peaks characteristic of geopolymerization; in the FTIR spectroscopy, the displacement of some bands by the incorporation of aluminum and in SEM images, the difference in morphology between pure slag and geopolymer, confirming the occurrence of geopolymerization.
