The capability of durable structure to resist weathering action during its service life But the fire accidents can occurred anywhere an time without any intimation .they can affected our human lives , property and environment . so we improve our structures against fire and build fire resistance structures .In this research fibers are used in concrete to improve fire resistance in concrete by partial replacement of fine aggregate with 0.6% of polypropylene fiber. To evaluate the comparison between polypropylene fiber reinforced concrete samples of M25 are casted and then fire test at temperature at 0 0 C, 400 0 C and 800 0 C. These samples provide the increased compression strength, split tensile strength and flexural strength of 7 days and 28 days. Polypropylene fiber reinforced concrete shows better fire resistance than conventional concrete at serve temperature .They occurs better resistance towards spelling and creep.
