High temperature causes serious damage to reinforced concrete structures on both nano scales and mesoscales. This damage shows a generalized mechanical property of concrete due to a sudden temperature of the structural effect due to the spalling of concrete, and the reinforcement bar tends toelongateinsuchhigh-temperaturecases. Duetothepertinenceofconcretematerialathightemperatureandinfl ame, numerousexaminations have been performed. Recently, there search was performed on cementitious materials at the level of heat by changing the pertinent measures. Inside this area, this research studies the effect of temperature on compressive strength, the stress-strain relationship for applying a load at a temperature in a steady-state condition in the oven and compares the results with the specimen at an elevated temperature of concrete. In addition, the bond slip of steel in concrete is also investigated. Among the goals of the paper, the methodology in this research enhances the concrete mechanical properties in the steady state at a high temperature. Also, the impact of the test modalities on the mechanical properties of concrete at high temperature is a lsodiscussed in the paper.
