Behavior of sisal fiber concrete cylinders externally wrapped with jute FRP

Abstract

The use of environmentally friendly natural fibers as building materials is benefit to achieve a sustainable construction. This article performs a study on the use of natural jute fibers as reinforcement of concrete and natural sisal fibers in fiber reinforced polymer (FRP) composites as concrete confinement, i.e. sisal fiber reinforced concrete (SFRC) composite column wrapped by jute FRP (JFRP) (SFRC-JFRP). Uniaxial compression test was conducted to assess the compression performance of the composite columns as axial structural member. A total of 24 specimens were tested. The effects of JFRP wrapping thickness and sisal fiber inclusion on the compressive performance of the composite columns were investigated. Results indicate that JFRP confinement significantly increases the compressive strength and ductility of both PC and SFRC with an increase in JFRP thickness. Besides, the inclusion of sisal fiber further enhances the strength as well as the efficiency of confinement under uniaxial compression. Also, the models for ultimate strength and ultimate strain of PC-JFRP and SFRC-JFRP are proposed

Bond-behavior study of newly developed bamboo-composite reinforcement in concrete

“…Organic materials such as jute, sisal, coconut coir and date palm are among some of the alternatives that have been used to replace steel. However, the tensile capacity of these materials is often too low when compared with steel [1][2][3][4].…”

Axial behavior of concrete confined with flax fiber-reinforced polymers

“…Some studies have been carried out on the use of natural materials instead of synthetic fiber materials, particularly as concrete confinement materials (Ghalieh et al, 2017;Tan et al, 2017;. In some of these studies, it has been stated that with two layers of flax fiber, the axial compressive strength was improved by 1.5 times and ductility by 8.5 times compared to unconfined concrete .…”

The Influence of the Curing Conditions on the Behavior of Jute Fibers Reinforced Concrete Cylinders

“…As stated by Hussain and Ali [7], the Jute fibers enhance crack resistance and toughness of concrete. According to Tan et al [8], the ultimate load of concrete columns has been increased by wrapping with JFRP composites. Alam and Al Riyami [9] showed that the toughness and strength of beams have been improved by the reinforcement using the natural fibers [10,11].…”
