【 摘 要 】

The geopolymer concrete is the new binding agent in place of cement and it utilizes the alternative materials like fly ash. This type of concrete is eco-friendly material as it does not emit the CO2 gases in the environment up to hazardous level. The polymeric reaction between fly ash and alkaline chemical activator solution like sodium silicate and sodium hydroxide to form gel is occurred in geopolymer concrete. The experimental work on the different proportion ratios of material used in the concrete mix and effect of rest period on the compressive strength of concrete cubes are tested. Sodium silicate is used based on its normality of 1N and 2N, sodium hydroxide is used of 12 molar. The rest period is considered for the test was 1, 2, 3, 4, 5 and 7 days. Thermal curing in hot oven under the controlled temperature of 60°C, 65°C, 95°C, 125°C and 135°C for 24 and 48 hours is considered. It was observed that for curing temperature of 90°C to 100°C shall give the good compressive strength.
