Structural Characterization of Geopolymers with the Addition of Eggshell Ash

It is well known that geopolymers are a new group of binder materials alumosilicate origin. Geopolymers made by the reaction precursor aluminosilicate with alkaline activator solutions. The current research relates to low-cost and eco-friendly procedure, suitable being implemented in two easy steps. first step production solid phase based on fly ash (Obrenovac, Serbia) eggshell as waste rich calcium. second alkali activating using an (a mixture NaOH Na2SiO3) procedures proper laboratory conditions. Four samples different content were synthesized. concentration used was 12 mol dm−3. structural properties all investigated analyzed XRD (X-ray diffraction), DRIFT (diffuse reflectance infrared Fourier transform), SEM (scanning electron microscopy) UV/Vis spectroscopy analysis. determined amorphous halo presence quartz crystal samples. These results confirmed morphology showed material could be potential adsorbent.
