Geopolymers are inorganic, amorphous aluminosilicate materials that can be formed by the polycondensation of aluminosilicate sources such as metakaolin or fly ash with alkali activators. They have gained attention as a more sustainable alternative to traditional cement-based materials, as they have lower carbon emissions and can use industrial by-products as feedstocks. Geopolymers have a range of potential applications in construction, insulation, and chemical resistance due to their high mechanical strength, durability, and fire resistance. Research in this area focuses on optimizing the synthesis methods, understanding the properties and behavior of geopolymers, and exploring new applications for these materials.
