Improvement The Concrete Fire Resistance by Using By-Product Materials

The utilization of lime within the cement manufacturing procedure yields a considerable quantity of carbon dioxide emissions, thereby contributing to the phenomenon of the greenhouse effect and the subsequent escalation of global warming. To mitigate the emissions, it is imperative to employ diverse materials during the manufacturing process. Granulated blast furnace slag, a finely ground aggregate derived from the byproduct of blast furnace operations, has found significant application in the realm of concrete production. This material, obtained from the blast furnaces, has proven to be highly advantageous in enhancing the properties of concrete. This study aims to investigate the utilization of Ground Granulated Blast Furnace Slag (GGBS) as a supplementary material in concrete, serving as a partial replacement for cement. The utilization of ground grainy blast furnace slag and RHA has been found to enhance the properties of concrete and can be incorporated in concrete production without causing any adverse impact on the surrounding environment. This makes it a sustainable and eco-friendly solution. The strength degradation of high strength concrete, both during and post-fire exposure, may exhibit dissimilar behavior when compared to that of conventional strength concrete. The primary objective of this review is to examine the alterations in concrete properties after fire exposure, while also investigating the potential of GGBS and RHA in enhancing the fire resistance of concrete.
