Effect of Bamboo Fibers in Fresh and Hardened Properties of Self Compacting Concrete

Abstract

Background/Objectives: An attempt has been made in the present investigation to assess the outcome of bamboo fibers on strength behaviour of FRSCC. An innovative natural plant bamboo fiber, having numerous benefits such as economical, low density, environmental-friendly, sustainable and biodegradeble. Bamboo fibers extracted by using mechanical method was used in this study. Methods/Statistical Analysis: Proportion of mix of SCC has been arrived by trial and error method. Nine trial mixes were investigated totally, keeping w/c quotient constant for all mixes and variation parameter is percentage of weight fraction of (0.25, 0.5, 0.75,1 and 1.25 %) of bamboo fibers (l/d ratio = 40) of 4.9 mm length to the weight of cement. Finally, 18 cubes, 18 cylinders and 18 beams casted, out of which 15 are BFRSCC beams, 3 are control beams without fibers made with SCC. Findings, Applications/Improvements: The outcome of using bamboo fibers in the strength behavior in compression, split tensile and the flexural had studied. The maximum enhancement in compressive and split tensile strength for 28 days was observed to be 43.2 N/mm 2 and 6.9 N/mm 2 , hence optimum fiber content is 1% for aspect ratio of 40. The addition of bamboo fibers also make concrete much resistive in flexure and for 28 days maximum improvement was resulted 8.1 N/mm 2 , consequently addition of bamboo fiber content increases the flexural strength.
