Geopolymer is an inorganic polymer formed from the reaction of materials rich in reactive silica and alumina mixed with an activator typically of alkaline solution resulting in two-dimensional or three-dimensional aluminosilicate polymeric networks.
Geopolymer technology has emerged as an attractive solution to valorize coal fly ash (CFA), and use this industrial by-product from thermal power plants to produce “green” construction materials. These would have a wide range of properties depending on the raw materials and process conditions. Its microstructure and macroscopic properties would depend on the various factors present in the raw materials, the type of activator solutions, and the process conditions.
Geopolymer-based materials offer not only the potential significant reduction in carbon footprint, energy consumption, but also provide an alternative material with good engineering and other specialized properties.
