The need to cure fly ash-based geopolymer at elevated temperatures has limited the
practicability and sustainability of the composite. Hence, there is an imminent need to find
ways at which fly ash-based geopolymers can be cured at ambient conditions. This paper
presents the results from the experimental investigation of the effect of lime and silica fume
on the properties of geopolymer concrete cured at ambient conditions. Lime and silica fume
were used as the partial replacement of fly ash as an aluminosilicate precursor and the …
