Abstract: The production and the utilisation of cement is increasing rapidly as the construction industry is growing day by day. Cement is very harmful to the environment as one kg of cement emits one ton of carbon-di-oxide. Production of geo-polymer concrete is also one of the best ways to reduce the pollution as this concrete completely omits the usage of the cement in the construction. This paper reviews about the influence of concentration of sodium hydroxide solution on strength parameters of geopolymer concrete. Flyash is taken from locally available factory. The molarity is varied from 8M to 14M. The specimens are heated at 60 ºC in hot air oven for 24hours. The results show that the geopolymer concrete has obtained its optimum strength at 12M for both 7 and 28 days. The results show that all mechanical properties of geopolymer concrete have the same optimum level achieved at same molarity. Results also states that, all the mechanical properties are improved than the normal concrete when compared to geopolymer concrete.
