El presente trabajo establece los comportamientos usuales de los materiales geopoliméricos, usando Difracción de Rayos X (DRX) y Espectroscopía de Infrarrojo (FTIR). Los resultados obtenidos muestran que el geopolímero contiene estructura amorfa pero a su vez diferentes fases cristalinas, principalmente zeolitas, las cuales se relacionan directamente con el activador alcalino utilizado, además los enlaces químicos que aparecen en las bandas de FTIR corresponden a moléculas presentes en los compuestos cristalinos que se manifiestan en los resultados de DRX. Por otro lado se afirma que la ceniza volante fue correctamente activada, debido a la presencia del gel de aluminosilicato sódico hidratado (N-A-S-H) indicada en los espectros de FTIR
This work establishing the behavior of geopolymeric materials using X-ray diffraction (DRX) and Infrared Spectroscopy (FTIR). The results show that the geopolymer containing amorphous structure but turn different crystalline phases, mainly zeolites, which are directly related to the alkaline activator, also the chemical bonds that appear in the FTIR bands correspond to molecules present in the compounds crystalline manifested in the XRD results. Furthermore is stated that the fly ash was correctly activated due to the presence of sodium aluminosilicate gel (N-A-S-H) indicated in FTIR spectra.
