The major problem the world is facing today is the environmental pollution In the construction industry mainly the production of Portland cement will causes the emission of pollutants results in environmental pollution. We can reduce the pollution effect on environment, by increasing the usage of industrial by-products in our construction industry.Geopolymerconcreteissucha one and in the present study, to produce the geo-polymer concrete the Portland cement is fully replaced with fly ash and the fine aggregate is replaced with granite dust and alkaline liquids are used for the binding of materials. The binder is the only difference to the ordinary Portland cement concrete. To activate the Silicon and Aluminium content in fly ash, a combination of sodium hydroxide solution and sodium silicate solution was used. Hence concrete with no Portland cement. The alkaline liquids used in this study for the polymerization are the solutions of Sodium hydroxide (NaOH) and sodium silicate (Na2Sio3). Different molarities of sodium hydroxide solution i.e. 8M, 12M and 14M are taken to prepare different mixes.
And the compressive strength is calculated for each of the mix.The Geopolymer concrete specimens are tested for their compressive strength hatthe age of 7days, mixes of varying sodium hydroxide molarities i.e.8M,12M and 14M are prepared and they are cured by direct sun-light and strengths are calculated for 7 days.
