Concrete structures are liable to be exposed to fire during their lifetime. After exposure to high temperature, the strength of concrete is determined only by its residual properties. The method of cooling, after exposure, is one of the significant factors in determining the residual properties of concrete. The compressive strength, tensile strength, stress-strain response and elastic modulus of concrete are the important properties to be considered in the design of fire resistant structures. In this paper, the behaviour of high temperature exposure of three different grades of concrete M20, M45 and M60 are considered. The specimens were subjected to high temperature regime of 100°C–900°C and were cooled by different methods. The maximum degradation of mechanical properties was observed between temperature regimes of 400°C to 600°C. High strength concrete was found to be more vulnerable compared to normal strength concrete. Mathematical models expressing the variation of different mechanical properties of concrete were developed and explained.
