Effect of Polypropylene Fibers on Freeze-Thaw Resistance, Surface Scaling and Flexural Toughness of Concrete
Fibers do not provide significant increase in the strength of concrete at low fiber volumes commonly used in practice. The main benefits of fibers result from the control of the width of cracks in concrete. Polypropylene fiber is one of the most popular polymer fibers used in concrete, which has been shown to be effective in controlling the plastic shrinkage at the content of approximately 0.1% by volume. However, as polypropylene fibers are low modulus fibers and used at such low contents, it is difficult to expect an improvement in the crack control of hardened concrete in theory. In the present study, the effect of a multi-filament polypropylene fiber on the resistance of concrete to surface scaling and freeze-thaw attack is investigated. Polypropylene fiber reinforced concrete was also tested under flexural load. Two different water/cement ratios were used for concrete production. The results indicated that polypropylene fibers can be beneficial in the control of micro-cracking induced by freeze-thaw cycling and surface scaling. The development of cracks under flexural load was not affected significantly by the presence of the polypropylene fibers.
