The use of waste items like silica fume, fly ash and ground-granulated blast furnace slag as a partial replacement for cement used in concrete has been considered a sustainable approach in the construction industry [13]. The amount of carbon dioxide gas emitted will be significantly reduced when GGBS is used in place of Portland cement.
