Porosity in any type of concrete makes a prominent role in strength, Permeability and Fracture properties. In this review study we can presents the investigation on effect of elevated temperature on fresh and hardened properties of concrete. High temperature is well known for seriously damaging micro and meso- scopic structure in concrete. The mechanical properties that are primary interest in fire resistance design are compressive strength, tensile strength, elastic modulus and stress strain response in compression these are the important parameters to be consider for designing fire resistance design of structures. Effect of elevated temperature is influence to both normal strength concrete (NSC) as well as high strength concrete (HSC). In this comprehensive review paper we can gives an overview of behavior of the structure in high elevated temperature. We mainly focused to compressive strength, thermo mechanical effect (stress distribution and cracking), local behavior (spalling and surface micro cracking) and micro structural behavior of concrete etc.
