Potential of Natural Fibres for Strengthening Existing Structures – A Review

Archana D. P.

Abstract

To rehabilitate the deficiencies in the existing structures, synthetic/artificial fiber reinforced polymer composites have been considered as an effective external strengthening material for construction industries since a long period, due to their outstanding performances like high strength-to-weight ratio, lightness, and resistance to corrosion. But few of their drawbacks in terms of high cost, environmental issues etc., they have been triggered the introduction and development of natural fibers. Natural fibres are renewable resources in many developing countries of the world; they are cheaper, pose no health hazards and finally, provide a solution to environmental pollution by finding new uses for waste materials. These fibers are substantially replacing synthetic composites as sustainable materials for the strengthening of reinforced concrete structures. The present paper aims to review the different natural fibers such as sisal, bamboo, roselle, silk and coir as reinforcement in polymer matrix composite and their suitability for strengthening of reinforced concrete structural members.
