Abstract

The development of fly ash based geopolymer concrete,  need of a ‘green’ concrete in order to reduce the carbon dioxide emission from the cement production. Portland cement is one of the most energy intensive construction materials. Every 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.  Fly ash is possible up to certain extent to reduce the cementing material due to pozzolanic activity of fly ash. Therefore it is necessary to activate the fly ash by using alkaline activators. In present study investigations sodium based activators are used. Sodium hydroxide solution having different molarities  concentration are used and Sodium silicate solution with Na2O  and SiO2  were maintained constant throughout the experimentation. Alkaline solutions might be sodium based or potassium based. Generally sodium based solution is used from economy and availability point of view.The experimental paper presents the cube test results of geopolymer concrete with different molarities of sodium hydroxide with various ratio of sodium silicate solution. The adopted mix design  of M30 grade  of geopolymer concrete procedure is relevant to previously adopted experimental study adopted by S.V.Patankar et.al(2013) carried the research of binder ratio in the production of fly ash based geopolymer concrete. This existing cement concrete Mix Design was applied to Geopolymer Concrete as experimental study to identify the  higher compressive strength of concrete cubes with different molarities of sodium hydroxide.
