Parametric study of Geopolymer Concrete
Abstract
The study analysis is the effect of temperature and curing time on compressive strength, split tensile strength and flexure strength. Geopolymer concrete is manufactured by replacing cement fully with processed low calcium fly ash which is chemically activated by alkaline solutions like sodium silicate (Na2SiO3) and sodium hydroxide (NaOH). In this study solution to fly ash ratio of 0.61 with 15 Mole concentrated sodium hydroxide solution is used and grade chosen for investigation was M30. All the specimens were cured in oven at 600C, 900C and 1200C for 6, 12, 18 and 24 hours duration. All tests were conducted according to Indian standard code procedure. Test results for compressive strength, split tensile strength and flexure strength are tabulated and discussed in details and some important conclusions are made. I
