| Abstract | ||||
| One of the primary physical factors that affects the durability of structures is high temperature. By causing long-term damage to the structures, this effect might render them unusable and result in the loss of life and property. This essay examines the constituent elements of concrete and how they affect the mechanical characteristics of concrete that has been exposed to high temperatures. The characteristics of the raw material, such as cementitious materials, aggregate, and fibres, have a significant impact on the concrete's behaviour at high temperatures. The primary findings of many studies on the best ways to use cementitious materials including metakaolin, slag, and fly ash to improve the characteristics of concrete are also presented in this study. Since aggregates make up a large amount of concrete, particular attention has been paid to the mechanical and thermal characteristics of various aggregate types at high temperatures. Finally, because to their greater tensile strengths, steel or polypropylene fibres can be used to improve the mechanical properties of concrete at high temperatures. | ||||
