An Experimental Study on Low-Calcium Flyash and Metakaolin Based Geo-Polymer Concrete IJTSRD
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.
