Summary:The present invention relates to a geopolymer mortar and to a method for obtaining such a mortar from mine tailings, which is straightforward and easy to carry out, without the addition of any other known binder (Portland cement or fly ash) and which has good mechanical properties under compression. The incorporation of a single hardening component (sodium hydroxide) is consistent with the aim of avoiding "additional variables" that increase the complexity of the process for manufacturing geopolymer mortars. El presente invento se refiere a un mortero geopolimérico y a un método de obtención de dicho mortero a partir de relaves mineros, el método es simple y de fácil realización, sin la adición de ningún otro aligante conocido (cemento Portland o ceniza volante) y que tenga buenas propiedades mecánicas en compresión. La incorporación de un único componente endurecedor (hidróxido de sodio) es consistente con el objetivo de evitar "variables adicionales" que aumenten la complejidad de proceso de fabricación de morteros geopoliméricos. La présente invention concerne un mortier géopolymère et un procédé d'obtention dudit mortier à partir de résidus de lavage miniers, le procédé est simple et facile à mettre en oeuvre, sans addition d'aucun autre liant connu (ciment Portland ou cendre volante) et présente des propriétés mécaniques en compression satisfaisantes. L'incorporation d'un unique composant durcisseur (hydroxyde de sodium) est cohérent avec le dessein d'éviter des "variables additionnelles" qui augmentent la complexité du procédé de fabrication de mortiers géopolymères.
