Application of geopolymer concrete is in precast industry therefore the main objective of this paper is to develop the geopolymer concrete for the preparation of pre-cast railway sleepers. The other objective is to reduce the consumption of energy in curing by adopting ambient(sunlight) curing. In the present study, alkaline liquid to fly ash ratios of 0.35 and 0.4 with 16Molarity and 18Molarity of NaOH solution were used. To determine the compressive strength for geopolymer concrete, specimens of size 15cm X 15cm X 15 cm cubes were prepared. The curing regimes adopted were steam curing at average temperature of 650C for 24 hours and ambient curing at average temperature of 400C for 7days. The compressive strength attained for alkaline liquid to fly ash ratio 0.4 and 0.35 for 18Molarity were in the range of 36.44N/mm2 to 60.35N/mm2 for ambient curing and 41.9N/mm2 to 72.09N/mm2 for steam curing. The compressive strength attained for alkaline liquid to fly ash ratio 0.35for 16Molarity were in the range of 58.88N/mm2 to 61.33N/mm2 for steam curing and ambient curing.
