Development and Applications of Advanced Geopolymer Gel Materials

Dear Colleagues,

A very small amount of the fly ash (FA) produced in power plants worldwide is used in construction annually; most FA ends up in open landfills and poses a serious threat to human health. Accumulated industrial residues from full landfills are suitable for use in the production of cheap and fireproof insulation materials as well as insulation materials with high conductivity and high compressibility, providing good protection against radiation. It is necessary to focus on the development of new, advanced geopolymer gel materials (AGGMs) based on fly ash and slag from industrial waste and reducing their impact on the environment. Such materials can be obtained by changing the process parameters during “green” synthesis, such as the type of precursor, the molarity of the activator, and the liquid/solid ratio, or by adding various additives to the gel phase. Slag- and FA-based geopolymer gel materials can be applied in various technological fields due to their excellent thermal stability and thermal shock resistance, high porosity, high sustainability, and low energy consumption during production. It is of great importance to monitor the physicochemical, mechanical, and thermal properties of some types of AGGMs and determine the possibility of utilizing them as new “green” materials. This Special Issue aims to disseminate knowledge on AGGMs and discuss their classification for application in various infrastructure fields. This Special Issue aims to disseminate knowledge on AGGMs and discuss their classification for application in various infrastructure fields. This Special Issue also aims to raise awareness of the harmful impact of industrial waste on human health and safety. This issue aims to provide an overview of recent advances in the contribution of nanomaterials and related technologies to sustainable development and future prospects in this field. We invite authors to submit experimental and theoretical original articles, perspectives, and review articles addressing these problems and similar topics.
