Paper Title:
Properties of Flexible Fiber and Rigid Fiber Reinforced Cement Concrete Used on Surface Layer of Wharf Pavement
  Abstract

Different fiber reinforced concrete was experimentally investigated by adding flexible fiber and rigid fiber respectively into C20, C30 and C40 plain concrete. First the workability of fiber reinforced concrete was tested. Then the mechanical property and frost resistance property was tested after curing on standard condition for 28 days. The flexible fiber is American Durafiber and domestic nylon fiber. The rigid fiber is domestic steel fiber. The result shows that fiber concrete can improve cohesiveness and water retention, the flexible fiber reinforced concrete presents more apparent. Compared with plain concrete, the slump and setting time decreases a little for flexible fiber reinforced concrete and increases a little for rigid fiber reinforced concrete. The compressive strength and flexural strength of fiber reinforced concrete can be increased compared with plain concrete. The rigid fiber reinforced concrete presents more obviously. For example, the compressive strength and the flexural strength of C30 concrete with the addition of steel fiber were increased by 24% and 34% respectively. The frost resistance of fiber reinforced concrete improves compared with plain concrete. The flexible fiber reinforced concrete presents more noticeably. For example, after 250 freezing-thawing cycles, the mass loss of C30 concrete with the addition of Durafiber is decreased by 15% and the relative dynamic elastic modulus is increased by 6% compared with plain concrete.
