Abstract:

Fire resistance of concrete structure is an important factor to be considered in the design of building. Fire may cause different degree of damage to the structure depending on the temperature and duration of its exposure. Adding of fibers in the concrete improves the residual strength and fracture energy. In this paper an experiment investigation has been carried out to study the impact strength of fiber reinforced concrete at elevated temperature. Specimens were heated from 27ºC to 500ºC and cooled by natural air and by water. Steel fiber (0.5% & 1%) and polypropylene fiber (0.5% & 1%) were added to enhance the fracture energy of concrete at elevated temperature. These specimens were heated by using Muffle furnace. After heating the specimens were allowed to cool naturally in the atmosphere for 24 hours in case of air cooling and sprayed water in case of water cooling. The Impact strength of specimens were compared with reference specimens (no fiber). The specimens with steel fiber showed higher toughness and impact strength after exposure to high temperature. The polypropylene could mitigate the spalling of specimens significantly.
