Strengthening of RC Beam using Numerous Natural Fibre Laminates - a Review

Abstract

Nowadays natural fibers are getting attention from researchers and scholars to use it for construction of buildings because of their sustainability and eco friendly nature. There are various natural fibers like bamboo, sugarcane fiber, coconut coir, sisal fiber, flax fiber etc., are available for construction. Aim of this paper is to give a detailed study about various experiments conducted on the reinforced concrete structure that are strengthened with fiber laminate. The failure load, ductility, crack pattern, strength properties, flexural behavior of reinforced concrete beam, viscous and mechanical properties and strain characteristics of strengthened beams with different natural fiber composite laminates are reviewed. The result shows that the strength, ductility and durability properties of concrete are increased according to their proportions.
