Abstract

Gcopolymer concrete is an alternative environmentally friendly product to replace Ordinary Portland Cement (OPC) concrete as main construction material around the world. '['his eco-friendly concrete material developed because of the needs to reduce the greenhouse gases emission, minimize waste and save the non-renewable resources as the effect of Ordinary Portland Cement production. This research was proposed to obtain the optimum mix proportion and curing method for geopolymer concrete with cast in-situ applications. Fly ash has been used as a source material for this research work while the alkaline solutions used in geopolymerisation is a combination of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). Different curing regimes have been applied to cure the geopolymer concrete to find the best curing method. Sucrose was utilized in the mixture to produce workable geopolymer concrete which is not too stiff and easily hardened. The compressive strength test done on the geopolymer concrete sample showed that external exposure curing provided superior performance compared to other curing method. It was also supported by the observation at microstructure level through FESEM test.
