Influence of Textile Fiber in the Mechanical Characteristic of Hybrid Fiber Reinforced Concrete

Abstract

ABSTRACT The early growth of micro-cracks develops due to plastic and dry shrinkage weakens conventional concrete’s mechanical properties; which can be improved by introducing discrete and randomly oriented natural and synthetic textile fibers, like sisal, banana, and nylon in concrete matrix. Previously, researchers focused only on double hybrid fiber reinforced concrete, whereas triple hybrid fiber reinforced concrete requires a further behavioral study on fiber reinforced concrete’s mechanical characteristics. In this paper, we investigate the mechanical properties induced by the addition of discrete and randomly oriented textile fibers to the cementing matrix in a varying volume fraction of 0.5% vf to 2% vf along with 1% vf triple hybrid. BF0.5% vf , SF1.5% vf , NF1% vf & HFRC (SF0.5BF0.25NF0.25) % vf gives optimum fiber dose in the composite. As a rule, the specimens gain impressive compressive strength. Most of them exhibit enhanced tensile properties compared to the control specimen. These developments signal the advent of an eco-friendly, economical, and highly sustainable alternative to conventional concrete.
