Hence reducing the greenhouse gas emissions, which is the reason behind global warming, is the need of the hour and so efforts are urgently underway all over the world to develop environmentally friendly construction materials, which make minimum utility of fast dwindling natural resources and help to reduce greenhouse gas emissions. Five to eight percent of the world’s manmade Greenhouse gas emissions are from the Cement industry itself. It is an established fact that the green house gas emissions are reduced by 80% in Geopolymer concrete vis-a-vis the conventional Portland cement manufacturing, as it does not involve carbonate burns. In this connection, Geopolymers are showing great potential and several researchers have critically examined the various aspects of their viability as binder system. Considerable research has been carried out on development of Geopolymer concretes (GPCs), which involve heat curing. A few studies have been reported on the use of such GPCs for structural applications. Thus Geopolymer based Concrete is highly environment friendly and the same time it can be made as high performance concrete. This paper presents a review of the literature, outlining the various research approaches undertaken in an effort to check the feasibility of geopolymer to Civil Engineering applications. The findings of these varying approaches are compared, and the different strategies employed are compiled and discussed. It is expected that this review will provide a key step in advancing the understanding of this innovative construction material.

Introduction Ordinary Portland cement has been a binder for Civil Engineering tasks for a long time. But at present, there are many new issues branching from its ever increasing use. Cement production consumes huge quantities of virgin materials, is energy-intensive, and leads to high emission of the greenhouse gas CO2, which is the main reason behind Global warming. Again, Sulphur dioxide emission also can be very high, depending upon the type of fuel used. Installation of new cement plants is becoming increasingly capital-intensive. Finally, many cement concrete structures have exhibited early distress and problems, which has an adverse effect on the resource productivity of the industry. To overcome all such limitations, a new cementitious composite called “Geopolymer” is evolved. The name geopolymer was coined by a French Professor Davidovits in 1978 to represent a broad range of materials characterized by networks of inorganic molecules. It is a type of inorganic polymer composite, which has recently emerged as a prospective binding material based on novel
