Effect of Different Variables on Fly Ash based Geopolymer Concrete - Vol.94(2), Feb - Mumbai ACC LTD 2020 - 62-68p.
In present research investigation, Fly ash based Geopolymer Concrete (FGPC) has been manufactured by full substitution of cement with unprocessed and processed fly ash. The effect of variables such as Ratio alkaline liquid to fly ash, sodium silicate solution to sodium hydroxide ratio, Concentration of sodium hydroxide, in Molar; Addition of superplasticiser, additional Water content, Curing temperature and time, Rest period on compressive strength of FGPC was examined. The results reveal that the optimum compressive strength of FGPC was obtained with sodium silicate to sodium hydroxide ratio as 2.5, plasticizer content of 2.0%, water content of 10%, curing time for 48 hrs, curing temperature at 90ºC and a rest period of 1 day.
