Geo-polymer concrete is a ‘new’ material that does not need the presence of Portland cement as a binder. Instead, the source of materials such as fly ash and GGBS that are rich in Silicon (Si) and Aluminum(Al),are activated by alkaline liquids to produce the binder. Hence concrete with no Portland cement. Fly ash was chosen as the basic material to be activated by the geo polymerization process to be the concrete binder, to totally replace the use of Portland cement. To activate the Silicon and Aluminum content in fly ash, a combination of sodium hydroxide solution and sodium silicate solution was used.

Keywords: Concrete, Fly ash, GGBS, Sodium hydroxide, Sodium Silicate
