Fly ash, ESP, Particle Size, Geopolymer CompositeAbstract
This study investigates the properties of fly ash-based composites using particles of varying sizes, sourced from the hopper located immediately before the electrostatic precipitator (ESP) and the final field hopper of the ESP. The research focuses on the development of geopolymer mortars, using sodium silicate and sodium hydroxide as alkali activators (AA). After curing and drying, the samples were analyzed for compressive strength, flexural strength and porosity to assess their physical characteristics. All tests were conducted to evaluate the mechanical performance of different fly ash and activator compositions. The microstructure of the geopolymer samples was examined using scanning electron microscopy, providing insights into the morphological changes associated with the activation process. This investigation highlights the potential of fly ash as a sustainable material for advanced geopolymer applications.
