This study has focused on using an encapsulation technique to stabilize the fly ash by a geopolymer. The potential of a geopolymer to stabilize fly ash was explored through the use of four geopolymer formulations. The leach rates of untreated fly ash helped to target of seven elements that are arsenic, barium, beryllium, selenium, strontium, calcium, and potassium. The lowest leach rates were observed at the geopolymer formulation with Si/Al=2.
