The geopolymer concrete is a developing unconventional binder with low eco-friendly effect and possible to increase sustainability of concrete construction. The cement has been substituted by fly ash and alccofine with varying different percentages. The testing methods carried out in this paper are compression strength, split tensile strength and flexural strength. In this paper, 10M sodium hydroxide was used. The result shows that GPC (geopolymer concrete) produced with fly ash and alccofine enhances the properties. Concrete cubes, cylinder and beam samples were casted and tested to obtain mechanical and durability properties of various mixes. © BEIESP.
