Abstract: Geopolymer binder is the invention in binding materials in the area of concrete technology and one-step towards the sustainable development in construction materials. Fly ash based geopolymer concrete requires the temperature curing for gaining the sufficient strength. However, practically in cast-in-situ condition it is not possible to provide the temperature curing to structural elements. In this experimental research, the ordinary Portland cement (OPC) was used as a curing agent in geopolymer concrete. Experimental investigation has been carried out to optimize the percentage of OPC for achieving the sufficient strength of fly ash based geopolymer concrete without external temperature curing. For that 0%, 2%, 4%, 6%, 8% and 10% OPC of that total fly ash were added in the mix as a curing agent. Sodium silicates and 14 molar sodium hydroxide were used as alkaline activator and solution to fly ash ratio was 0.40. The effect of percentage of OPC on workability and compressive strength of geopolymer concrete were evaluated. The results show that, the compressive strength increases when increasing the percentage of OPC in the mix up to 10%. Geopolymer concrete with OPC achieves the similar strength as to geopolymer concrete with temperature curing.
