The present study presents a comprehensive summary of the extensive studies conducted on fly ash based Geopolymer concrete. Test data are used to identify the effects of salient factors that influence the strength properties of the Geopolymer concrete. Geopolymer concrete can be manufactured by adopting the conventional techniques used in the manufacture of Portaland cement concrete. Low calcium fly ash is used as the source material instad of Portland cement to make concrete. Heat curing of low calcium fly ash based Geopolymer concrete is generally recommended. From the study it is clear that optimum curing temperature is 800 C and as the concentration of sodium hydroxide increases, compressive strength of the Geopolymer concrete increases. Geopolymer concrete produced with NaOH in concentration of 8M cured at 800 C yields a compressive strength of 18.44 MPa.
