Alkali activated materials (AAMs), also named geopolymers or inorganic polymers, are materials that are produced when alkaline solutions react with precursors containing aluminosilicate phases. The most commonly used alkaline solutions, include sodium or potassium hydroxides and/or silicates, while aluminosilicates may include suitable raw materials and by-products/wastes produced from various industrial processes. AAMs can be commercialized in various industrial sectors. When AAMs are produced with the use of industrial wastes, including for example metallurgical slags of various types, fly ashes, bauxite residues, construction and demolition wastes or leaching residues, the benefits are twofold. They also include the valorization of these wastes for the production of value added products and the substantial reduction of the environmental footprint of the construction sector, due to the considerable savings of virgin raw materials.This Special Issue of Minerals includes 14 papers highlighting the advances and future trends in alkali activation of wastes for the production of AAMs that can be used as sensors, adsorbents, catalysts, pH modifiers, as well as for the production of zeolite foams, low carbon binders, cemented paste backfill, alkali activated mortars and concrete. Furthermore, the elucidation of mechanisms involved during alkali activation, as well as the mineralogy, microstructure and properties of AAMs with the use of advanced techniques are discussed. All these papers aim to attract the interest of the readers and especially of young scientists and students at graduate and post-graduate levels in this very important scientific field.
