    Abstract :

    Every year production of cement increases with increasing demand of construction Industries. Therefore rate of emission of carbon dioxide into the atmosphere also increases. Portland cement is one of the most energy intensive construction materials. Each ton of Portland cement releases a ton of carbon dioxide into the atmosphere. On the other side fly ash is waste material available from thermal power plant. Replacement of cement by fly ash is possible up to certain extent due to pozzolanic activity of fly ash. For complete possible of cement by fly ash, it is necessary to activate the fly ash by using alkaline activators. In present investigation sodium based activators are used. Sodium hydroxide solution having different molarity concentration is used & Sodium silicate solution with Na2O = 15.06%, SiO2 = 34.01% , H2O = 50.93% were maintained constant throughout the experimentation. Geopolymer technology is new technology in which pozzolanic material which is rich in silica and alumina is used and it is activated by alkaline activators. Alkaline solutions may be sodium based or potassium based. Generally sodium based solution is used from economy and availability point of view.
