✦ Synopsis
A study on behavior of cement based matrices reinforced by randomly distribu ted microfibers is summarized. Effects of volume fraction, length and type of fiber, and type of cement based matrix were experimentally examined using uniaxial tensile specimens and three-point bend beams. The matrix fracture properties were measured by a RILEM recommended test procedure. A confocal microscopy technique was used to measure fracture surface roughness, a parameter that was shown to correlate with fracture properties. By incorporating the obtained matrix fracture properties, fiber aspect ratio, and fiber-matrix interface bond into a fracture mechanical R-curve approach, mechanical responses of cement based matrices reinforced by fibers can be predicted.
