摘要：The fiber reinforced concrete with flexible fiber and rigid fiber respectively added into C30 plain concrete, curing under standard condition for 28 days, was used for impact resistance performance experiment. The flexible fiber is American Dura fiber and Chinese nylon fiber. The rigid fiber is Chinese steel fiber. The impact resistance property was evaluated by initial cracking times, final cracking times and impact toughness. The result shows that the impact toughness of steel fiber concrete, Dura fiber concrete and nylon fiber concrete is respectively 15.1, 3.4 and 2.7 times of the Plain concrete. The fiber reinforced concrete improves the impact resistance property compared with the plain concrete. The impact resistance of rigid steel fiber reinforced concrete is increased greatly.
