The material used in the construction where it is suitable for placing the concrete in difficult conditions and in structures with congested reinforcement is called High Strength Concrete. In case of unexpected fire, the concrete elements such as beams, columns etc. will be subjected to extreme temperatures and need for assessment of their performance after fire. Soitis proved that it is important to understand the change in the concrete strength properties due to extreme temperature exposure. This paper shows that assessment of effect of sustained temperatures on strength properties of High Strength Concrete and its comparison with ordinary Conventional Concrete. In order to study effect of sustained elevated temperature on the compressive strength, flexural strength, tensile strength of High Strength Concrete and ordinary concrete, the specimens of the concrete which are tested in laboratory are High Strength Concrete and ordinary conventional concrete .For various tests 9 cubes (150mmX150mmX150mm), 9 cylinders were cast and same for the ordinary concrete. The results obtained were compared with the corresponding properties of normal concrete with the same water cement and air content.

Keywords- Aggregates, ordinary Conventional Concrete, compressive strength.
