Abstract

Fiber matrix bond characteristics can be changed by treatments of the fiber surface. The effect of such treatments on the fiber reinforced concrete (FRC) tension-softening behavior and crack resistance is studied in this paper. Various R-curve behaviors are predicted based on a simple double cantilevered beam (DCB) model using the experimentally derived tensionsoftening curves. The result suggests that fiber surface treatments can substantially alter the composite fracture resistance as measured by the R-curve.
