Laminated Jute and Glass FibreReinforced Composite forRepairing Concrete Through Wrapping Technique

Abstract

Natural fiberreinforced composite in concrete structure material has attracted many researchers and engineers in recent decades due to its good agreement in mechanical properties, economics, and sustainability. An experimental investigation was conducted to investigate the jute and glass fiberlaminated composite for cylindricalconcrete repair.Jute and glass fiberwere used as reinforcement, and vinyl ester (VE) served as the matrix.The vacuum bagging technique was used to wrap the cylindrical concrete columns with a diameter of 50 mm and a height of 150 mm.Compression and Brazilian tests were performed on the specimen.It was discovered that the four (4) layers of jute fiberreinforced thermoset (JFRT) composite had the highest mechanical properties, with an improvement of 72.62%when compared to glass fibrereinforced thermoset (GFRT) composite. It can be concluded that both GFRT and JFRT had the potential to improve the mechanical properties performance of cylindrical concrete specimens with an increase of up to five (5) layers of woven fiber.The results presented here may facilitate improvements in the concrete specimen by using JFRT where it was suggested to have a higher improvement for the concrete specimen with the optimum layers applied.As a result, jute fiberhas been shown to perform better and can be used as an alternative to glass fiber.As a result, jute fiberhas been shown to perform better and can be used as an alternative to glass fiber.
