Hybrid fiber reinforced concrete (HFRC) is defined as a concrete that contains more than one fiber. Polypropylene fiber and steel fiber are the two fibers added in the concrete. The spalling of the concrete is controlled by adding polypropylene fiber. Hooked end steel fiber is used for their anchorage. The Polypropylene fiber and the Steel fiber have great synergetic effect, so that their binding increase the strength of the concrete. Three types of concrete were used, concrete without fiber, concrete with mono fiber and concrete with hybrid fiber. In all these types with fiber, steel fiber percentage (1%) remains same, only the polypropylene fiber is added in different proportions (0.25% and 0.5%). The mechanical property of the concrete shows that the fiber reinforced concrete performs better than the normal reinforced concrete. The fire resistance of the concrete beam with hybrid fiber is tested by exposing it to high temperature. The beams made of hybrid fiber reinforced concrete is heated to a high temperature of about 300°C for a period of 120 minutes. The inclusion of fiber to the concrete slows the occurrence of the crack and boosts the concrete's strength at elevated temperature. [ABSTRACT FROM AUTHOR] |
