A review of mechanical properties of fibre reinforced concrete at elevated temperatures
Abstract Fibre reinforced concrete (FRC) has gained increasing interest in recent years due to its superior mechanical properties compared to normal concrete. To apply FRC in civilian and strategically important buildings and other infrastructures, fire resistance is an inevitable matter of concern. According to the existing test results, different fibre types, fibre dosages and cementitious matrix designs would affect the fire resistance of FRC. This paper presents a comprehensive review of the recent research works on the fire resistance of FRC. In particular, the temperature-dependent mechanical properties of steel fibre reinforced concrete, polypropylene fibre reinforced concrete and hybrid fibre reinforced concrete are discussed, including permeability, spalling, compressive strength, tensile strength, elastic modulus, toughness and mass loss. In addition, the currently available predicting equations for FRC residual properties are summarised and compared.
Highlights Studies on the effect of elevated temperatures on FRC properties are reviewed. Influencing factors on the temperature-dependent FRC properties are discussed. The effects of reinforcing fibres are compared in detail. The existing predicting equations are discussed.
