The concrete which remains reinforced with fibers exhibits the tensile strength which is high at 200C. After subjecting the specimens to 4000C it was observed that the tensile strength gets reduced. High performance concrete specimens subjected to 6000C show the lowest tensile strength among all the specimens. With the increase in construction of high growth buildings, High performance concrete with increased toughness and durability properties will be of great material in construction industry. To know about the enhancement in strength and resistance to temperature after fiber addition, study of mechanical properties is needed. High Performance High Strength Concrete tends to create shrinkage cracks, so that the study of durability properties is needed.
