Abstract

This study aims to investigate the behavior of Ferro-cement confined plain concrete (i.e., ultimate load, failure mechanism, damages, and ductility) under both compression and split tension. The main motivation of this study was the research gap concerning the split tensile behavior of Ferro-cement confined concrete. In the experiment, Ferro-cement confinement method (i.e., monolithic and non-monolithic casting of Ferro-cement around concrete cylinders) and wire mesh content were the main variables. For each confinement method, Ferro-cement with wire mesh contents of 0.22%, 0.25% and 0.50% were considered. The test results demonstrated a notable capacity enhancement of concrete with Ferro-cement confinement under both compression and split tension. In the test, cracks were originated and propagated radially from the outer Ferro-cement shell towards the concrete core under compression, whereas cracks were generated and propagated in the opposite way under split tension. More damages, i.e., residual crack widths, were observed at the location of initial crack formation, irrespective of the parameters of this study, under both loadings. In addition, no distinct relationship was found between the displacement ductility and the parameters of this study.
