This paper has investigated the effect that temperature variation has on the properties of concrete with steel and synthetic fibre additions. The range of performance characteristics were determined at room temperature (20°C) and ±40°C of room temperature. Standard test methods were carried out in order to determine the flexural strength, bond strength and toughness of fibre reinforced concrete at varying temperatures. In many countries across the world, large fluctuations in temperature may be encountered. In countries such as Russia, Greenland and Canada, the temperature varies massively over the four seasons. It is therefore crucial to effectively predict the thermal behaviour of building materials in order to properly design structures which are capable of withstanding such extreme conditions. The temperature parameters used in the research represent the effect of real world temperatures, such as those recorded in the Middle-East and Canada (DeRosa, 2012).
