Rapid urbanization depends on basic infrastructural facilities. The National Housing and Habitat Policy evolved in 2007 stressed on utilization of eco friendly materials in construction field. From the construction point of view the demand of concrete is increasing day by day for satisfying the need of development of infrastructure facilities. It is a well established fact that the production of OPC not only consumes significant amount of natural resources and energy but also releases substantial quantity of Carbon dioxide to the atmosphere. Therefore, it is essential to find alternatives to make the concrete environment friendly. Geo polymer is an inorganic alumina silicatecompound, synthesized from fly ash. The fly ash, one of the industrial waste material from Thermal power plants becomes a source material for Geo-polymer binders, is available abundantly in India, but to date its utilization is limited. Hence it is essential to make the efforts to utilize this by-product in concrete manufacturing, which was suggested in Energy Conservation Building Code ECBC 2009. The experimental work on Geo-polymer concrete by using of fly ash to evaluate the effect of various parameters affecting itsstrength and durability of concrete in order to enhance its overall performance was carried over. The addition of naphthalene based Superplasticizer improves the workability of fresh geopolymer concrete. By applying the Nano Technology,Nano silica and Nano carbon is added to improve the strength of concrete. The main objective of this study with review of literatures is to analyze the carbon dioxide free cementitious material, itsvarious properties and their effects on Geopolymer concrete
