Tensile Response of HPFRC Composites Using Twisted Polygonal Steel Fibers
The study investigates the tensile stress strain response of cement composites reinforced with newly developed twisted polygonal steel fibers. A prototype machine developed for this research produced the fibers for the study. Parameters investigated include: volume fraction of the fibers; fiber equivalent aspect ratio; and the compressive strength of the mortar matrix. The high performance fiber reinforced cement composites exhibiting strain hardening and multiple cracking behaviors can be obtained with a proper combination of the parameters. Also provided is a comparison with hooked and straight steel fibers.
