· The GGBS also taken at two levels such as 22% and 27%, respectively. According to the results, fly ash has higher compressive strength with respect to greater replacement percentage of FA with GGBS in geopolymer concrete. This is because of rise in alkalinity of mix that further up surge the geo-polymerization rate.
