Influence of hybrid fibers on serviceability of RC beams under loading and steel corrosion

The results show that the presence of fibers decreases the corrosion level of bars, but fibers do not affect the corrosion potential. The assessment of corroded bars by the volumetric mass loss method reveals that the presence of fibers mitigate the severity of localized corrosion. The fibers reduce the corrosion cracking and deflection in comparison to the beam made of plain concrete. The observation indicates that the selection of a proper combination of fibers can significantly improve the service life of beams from structural and aesthetic viewpoints.
