Presentado en el V Seminario Peruano de Geoingeniería.Por: Yibran Perera, Ahmadreza Hedayat, Nan Zhang y Linda Figueroa, Colorado School of Mines, y Héctor Bolaños, Reynaldo Canahua, Isaac Yanqui y Néstor Tupa, Universidad Nacional de San Agustín de Arequipa.AbstractThis paper offers a description of the geopolymers materials production based on gold Mine Tailings (MT) from the city of Arequipa in Perú, and additivated with Calcium Hydroxide (CH) nanoparticles at concentrations of 1, 2 and 3 wt% of the MT. The factors affecting the geopolymerization process, their microstructural characteristics, as well as the mechanical properties of the final geopolymers are shown. The characterization techniques used in this study were X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), High Resolution Transmission Electron Microscopy (HRTEM) and the mechanical properties of the systems obtained were measured through uniaxial compression tests (UCT). The results show an increase in the compressive strength of the geopolymeric systems when additivated with CH nanoparticles.
