Geopolimer Berbasis Abu Terbang (Fly Ash) Boiler Pabrik Pulp Dengan Penamba…

Abstract Geopolymer has been successfully synthesized from boiler fly ash with the addition of Graphene Oxide (GO). The addition of graphene oxide is to enhance the mechanical properties of organic fly ash based geopolymer. Graphene oxide was made by using graphite from used batteries via Hummer method. The resulting graphene oxide solution was mixed with an alkaline activator solution (NaOH…
