This paper presents the outcomes of the experimental program conducted to study the mechanical properties of concrete homogeneously reinforced with biofibres like Sida cordifolia plant fibre (SICOF), Pineapple leaf fibre (PALF), Banana fibre (MUSAF) and Bagasse (BAGAF). The optimum content of fibre to be used is determined by conducting an experimental study on MUSAF and it is found to be 0.25 % by weight of concrete. The performance of this biofibre reinforced concrete (BFRC) is evaluated by conducting strength tests like compressive, split tensile and flexural strength tests in accordance to Indian standards. The results when biofibres are used in concrete individually shows that MUSAF and SICOF are good in improving compressive strength and split tensile strength, respectively. Scanning Electron Microscopy (SEM) images indicate that there is good bonding between these biofibres and concrete matrix. In this study, also an attempt has been made to check the performance of biofibres when used in combination. Thecombinations tried are SICOF-PALF (SP), SICOF-MUSAF (SM), SICOF-BAGAF (SB) and PALF-MUSAF (PM). Out of these, the combination SM gave excellent results both in improving compressive and split-tensile strengths of concrete.
