Abstract: Geopolymers (gp) are amorphous inorganic polymers, formed by alkali activation of geopolymer source materials (gsm) such as fly ash and slags using an alkaline activator solution (aas). Concretes made using geopolymer binders can be preferable alternative to the ordinary portland cement (opc) concretes from considerations of strength, durability, and ecology. Many industrial waste materials can act as gsms and this could reduce the environmental damages due to their unscientific dumping/disposal. Geopolymer concrete technology could significantly reduce co2 emission to the atmosphere as use of high energy intensive and lime stone based portland cement can be completely eliminated thereby reducing the carbon footprint of the construction industry and thus helping to reduce global warming. This aspect is discussed in this paper by considering a typical residential building through computation of quantity of concrete used. The data shows that there is considerable reduction in co2 emission and also significant savings in energy if gp is used instead of opc.
