Effect on strength of geopolymer concrete by alkaline activator

Author(s): Sagar Chavan, Ganesh Kumbhar
Abstract: Cement industry is one of the major contributors to the emission of greenhouse gasses. That is cement production consumes huge amount of virgin materials in atmosphere, which is one of cause of global warming. Also, in India more than 100 million tons of fly ash is produced annually. Which acts as a binder instead of cement in concrete. The activators were used like sodium hydroxide, potassium hydroxide and 50% of sodium hydroxide, 50 % of potassium hydroxide. In this study solution to fly ash ratio of 0.35 with 13 Mole concentrated sodium hydroxide solution and potassium hydroxide is used and grade chosen for investigation was M30. All the specimens were cured in oven at 600C, 1000C and 1400C for 12 and 24 hours duration. All tests were conducted according to Indian standard code procedure. Test results for compressive strength, split tensile strength and flexure strengthare tabulated and discussed in details and some important conclusions are made.
