Geopolymer concrete has become a potential candidate to replace Ordinary Portland Cement concrete in the construction industry due to its lower greenhouse gas emissions. It further proves to be environmentally friendly because it uses fly ash which is a by-product of coal that would otherwise end up as landfill. Its use is, however, lim-ited by a concern regarding increased brittleness and a lack of understanding of its behaviour under multi-axial load-ings. Ductility of geopolymer concrete columns can be increased by lateral confinement. The conventional confine-ment with steel reinforcement may not always be adequate to provide the ductility levels desired by the engineer. Confining pressure applied by FRP is a function of the lateral strain of concrete. The proposed project aims at under-standing the complete deformational behaviour of this greener material with different levels of carbon fibre rein-forced polymer (CFRP) and glass fibre reinforced polymer (GFRP) confinement.
