Geopolymer cement is the result of the polycondensation process of aluminosilicates, present in a mix of inorganic materials, that is induced by the action of an activating alkaline (or alkalination) solution. The geopolymerization process yields a three-dimensional structure of polymeric Si-O-Al bonds that enables the geopolymer cement to harden and develop considerable mechanical strength at room conditions. Apart from the most commonly used raw materials, namely, metakaolin, fly ashes, and slags, several inorganic waste materials, including waste glass, waste from natural stone processing, mine tailings, and ceramics waste, contain fractions of reactive aluminosilicates in their composition which turns them into potential raw materials for the production of geopolymer cement, contributing to a circular economy approach to building materials. Furthermore, geopolymer cement key properties, including fast setting and strength development, high durability, and low environmental footprint, might turn it into a viable and eco-friendlier alternative to ordinary Portland cement for some specific applications. This paper provides a review of the research conducted in the framework of geopolymer cement development, covering topics from its basic structure and synthesis physicochemical mechanisms to its final properties and applications.
