AbstractFor use in fire resistance calculations, the relevant thermal properties of high strength concrete were determined as a function of temperature. These properties included the thermal conductivity, specific heat, thermal expansion and mass loss, of plain and steel fibre-reinforced concrete made of siliceous and carbonate aggregate. The thermal properties are presented in equations that express the values of these properties as a function of temperature in the temperature range between 0°C and 1000°C. The effect of temperature on thermal conductivity, thermal expansion, specific heat and mass loss of HSC is discussed. Test data indicate that the type of aggregate has significant influence on the thermal properties of HSC, while the presence of steel fibre-reinforcement has very little influence on the thermal properties of HSC.
