Nano silica based geopolymer concrete shows excellent strength at room temperature. Flexural strength of 12GC6 reinforced concrete beam is higher than 12GC0H and CC. Bond performance of rebar with 12GC6 concrete is better than that of 12GC0H and CC. Nano silica enhances the geopolymerization process at ambient temperature.
