Abstract: Nowadays Environmental pollution is the major problem faced by the world. The emission of pollutants by construction industry during production of Portland cement are the main causes for environmental pollution. With the increase in use of industrial by products in our construction industry the pollution effect on environment can be reduced. Geopolymer is the one which uses by products and are environmentally friendly. In the present study to produced geopolymer the Portland cement is replaced with fly ash and fine aggregate is replaced with quarry dust and for binding materials alkaline are used. In this study for polymerization the alkaline solutions used are sodium hydroxide (NaOH) and Sodium silicate (Na2Sio3) solution. To prepare different mixes different molarities of sodium hydroxide solution i.e. 6M and 8M and comprehensive strength is calculated for each mix. The size of cube specimen considered are 150 mm x 150mm x 150mm.The comprehensive strength of geopolymer concrete specimen are tested at the age of 7,28 and 56 days. Mixes of different molarities 6M and 8M are prepared by varying the sodium hydroxide flakes amount in grams which are then cured in lab atmosphere and their strengths are calculated for 7,28 and 56 days. The results show that with the increase of the molarity of sodium hydroxide solution the comprehensive strength increases.
Index terms: Fly-Ash, Mortar, Fine aggregates, NaOH, Na2Sio3.
