Geo-polymer concrete is known as one of environmental- friendly construction materials. Using by-product material such as flyash and metakaolin replace cement would avoid carbon dioxide (CO2) emission during the manufacturing process of ordinary Portland cement (OPC). The objective of his research work was to produce a carbon dioxide emission free cementious material. This paper discusses low-calcium Flyash and metakaolin based geo-polymer concrete with different proportion of binder and molarities. The alkaline liquids used in this study for the polymerization are the solutions of Sodium hydroxide (NaOH) and sodium silicate (Na2Sio3). In this paper variation of source material for low-calcium Fly ash and Metakaoline and at various molarities like 10M, 12M and 14M is done to achieve compressive strength for medium grade of concrete of M-25. They are curing by oven at 600C for 24 hours then after ambient temperature. It is found that geo-polymer concrete with Metakoline and low-calcium Fly ash as increase its strength and shows good strength with increase in the molarity of the alkaline solution also comparable with that of Ordinary portland cement concrete.
