Abstract
The effect of temperature variation on concrete properties with steel and synthetic fibre additions was examined. 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. A significant increase in the performance of concrete was observed at a temperature of -20°C as well as a minor decrease in performance at temperatures of 60°C. Steel fibre concrete performed best within the parameters of this test. However synthetic fibres provided the optimal performance based on the flexural strength percentage change when compared to the control and steel fibre samples.
