Rheological and Mechanical Properties of Kenaf and Jute Fiber-Reinforced Cement Composites

Abstract This study investigated the rheological and mechanical properties of cement composites with kenaf jute fibers for use in shotcrete. The length volume fractions fiber were varied; analyzed terms air content, compression flexural tests conducted, degree dispersion was assessed using fluorescence microscopy. rougher surfaces led to a higher yield stress viscosity composite compared fibers. 10-mm-long at 2.0% fraction optimal while 30-mm-long 1.0% resulted worst properties. plastic exhibited positive negative correlations fraction, respectively. likely because bridging fluid actions bubbles content. For given only increases an increase length. Although all deteriorated (compressive strength decreased from 27.5 6 MPa, 6.2 1.8 MPa), mixtures failed ductile manner. Using induced dispersion, whereas minimum dispersion-coefficient value found 5-mm-long 0.5%.
