The composite's viability and sustainability have been constrained by the requirement to cure fly ash-based geopolymer at high temperatures. Finding methods to cure fly ash GGBS-based geopolymers under ambient conditions is therefore urgently needed. The effects of lime and silica fume on the characteristics of geopolymer concrete cured under ambient conditions are experimentally investigated and the results are presented in this work. The fresh, strength, and microstructure of the geopolymer concrete were studied as a result of the partial replacement of fly ash as an aluminosilicate precursor with lime and silica fume . The results of this investigation demonstrated that raising the silica fume content increases the slump and set ting times of the geopolymer concrete while increasing the lime content decreases them. The best compressive strength was also produced when lime and silica fume, at 7.5% and 2% respectively, were used in place of fly ash. An examination of the microstructure revealed that the GPC's use of both lime and silica fume produced a densified microstructure
