AbstractFor use in fire resistance calculations, the relevant thermal and mechanical properties of steel fibre-reinforced concrete were determined as a function of temperature. These properties included the thermal conductivity, specific heat, thermal expansion and mass loss, as well as the strength and deformation properties of steel fibre-reinforced siliceous and carbonate aggregate concrete. The thermal properties are presented in equations that express the values of these properties as a function of temperature in the temperature range 0-1000°C. The mechanical properties are given in the form of stress strain relationships for the concretes at elevated temperatures. The results indicate that the steel fibres have little influence on the thermal properties of the concretes. The influence on the mechanical properties, however, is relatively greater than the influence on the thermal properties and is expected to be beneficial to the fire resistance of structural elements constructed of fibre-reinforced concrete.
