Concrete structure repair along with rehabilitation has turned into one of the most prominent construction projects in the world. The effect of fire is seen in all constructions, regardless of their degree of precision. As a result, fire concerns in design have become an important part of structural engineering. Fire-related fire accidents may severely damage a building, causing it to collapse. This research looks at the research that was published from 1998 to 2022. The research makes use of a bibliographic technique based on the Scopus collection. This article compiles data from Scopus and contains 625 publications with the needed keywords such as high temperature and rehabilitated Reinforced Concrete (RC) structures such as beams, joints, and frames. A new rehabilitation strategy for improving their characteristics is provided. Then, a few of the works on the impacts of concrete on fire exposure in different conditions were addressed. However, several findings related to high temperatures and RC structure restoration were documented. Furthermore, the quantitative analysis will select papers based on a range of characteristics, such as the nations with the most papers, the sources with the most papers, the keywords that occur most often, and the articles with the most pertinent work. This review research will provide you with a qualitative as well as quantitative overview of the high-temperature investigations completed in RC structures.
