Enhancement of Concrete Sustainability under Temperature Variation using Hybrid Fibre Reinforcement


This study focuses on the performance enhancement of concrete structures under adverse conditions using hybrid fibre reinforcement. A carefully designed slag based concrete mix was arrived based on the three phase particle interaction with a significant reduction in the total cement content. Longer and shorter combination of steel (60mm and 35mm) and polypropylene (47mm and 23.5mm) fibres were used in this study subjected to temperature variation (200°C, 400°C, 600° C and 800°C). Many studies proved the performance of fibre under temperature variation but this study elaborates the significance of the type and size of fibres contributes to the sustainability of the concrete under adverse condition. The comparative assessment is made to understand the performance of each fibre combination under temperature effects. Test results show each hybrid combination shows better results than plain concrete and it purely depends on the fibre used. Even though the role of fibre is less in case of compressive strength but the effect of temperature on the type of fibre is clearly showcased elaborately in this paper.
