Axial Compressive Behavior of Rope Fi Reinforced Polymer Composite Concrete

Abstract

Abstract-This study presents results of an experimental investigation conducted to investigate the axial compressive behavior of rope fiber reinforced polymer (RFRP) composite concrete. Natural fiber ropes such as coir, coconut and hemp ropes are easily available both in developing and developed countries. In this study, rope fiber reinforced polymer composite is developed by applying epoxy resin to the natural fiber ropes. The natural hemp rope was applied in three different thicknesses, i.e., one layer, two layers and three layers. Both confined and un-confined concrete columns were tested under monotonic axial compression. The results indicate that rope confinement along with epoxy resin is a very effective method to enhance ultimate strength and strain of confined concrete. The confinement level has a significant effect on the strength and ductility of rope confined concrete. There is found a significant increase in strength and ductility of concrete with an increase in the confinement level.
