Cement, fine aggregates, coarse aggregates, and water are all used to make concrete. It serves as a white cell in the creation of enormous infrastructure, such as buildings, highways, and bridges. Ordinary Portland cement is the primary component in concrete manufacture. The use of lime in the cement manufacturing process results in a substantial amount of carbon dioxide emissions, which contributes to the greenhouse effect and global warming. As a result, in order to decrease such emissions, you must utilise different materials in each manufacture. Ground granulated blast furnace slag, which is derived from iron blast furnaces and may be utilised in concrete production, was one of the beneficiaries. The use of GGBS as a partial substitute for cement in concrete is examined in this study. GGBS was discovered to improve the qualities of concrete and to be used in the manufacturing of concrete without dumping into the ground, making it an environmentally friendly product. To analyse the impacts on concrete in terms of colour and strength characteristics, concrete specimens of grades M30 and M35 are induced into a temperature range of 200oC to 800oC in phases and then observed and measured. Furthermore, because fires do not occur in a controlled setting such as a furnace, the specimens are exposed to open flames to imitate the conditions in a real-life fire catastrophe structure, and the results are recorded.
