Abstract
The High Strength Concrete (HSC) is relatively higher brittle nature than normal concrete. Addition of fibre in concrete enhances the ductility properties. In the present research, agricultural products such as coir fibre (CF) and banana fibre (BF) were used to investigate the performance of HSC. The Fibre Reinforced High Strength Concrete (FRHSC) was developed with ternary blended combination using Metakaolin and Micro Silica. The concrete grades of M60 and M70 were designed for the study purpose. The fibre were added with 1.5% of volume of concrete and established three hybrid fibre combination such as 25% CF + 75% BF, 50% CF + 50% BF and 75% CF + 25% BF of total fibre content. The workability of FRHSC was maintained in the range of 100-120 mm with the assistance of superplastizer. The performance of FRHSC was determined using mechanical properties including the strength ratio and compared with the control HSC. The material performance of hybrid FRHSC was significantly improved and the ductility nature was increased up to 25% than the control HSC
