Investigation on Axial Capacity of Circular Concrete Columns Confined with Ferrocement Pre-Jacketing
Abstract
This paper presents an experimental study on axial capacity of circular concrete columns confined with
Ferrocement pre-jacketing. In this research woven mesh is used as a pre-jacketing material to improve the behavior of
structural circular column under axial compression load. The confinement effect over the circular column is uniform
compared to the same of a non-circular column. In this study total 6 specimens are tested where crushed stone and clay
burnt brick chips used as a coarse aggregate. For comparing the increased capacity of stress and strain with jacketed
specimens, 2 specimens are non-jacketed as control specimen. Confined specimens showed higher strength than the
unconfined specimens under compressive load. Besides, the stress–strain behavior indicates that double layer of
Ferrocement jacket provides significant confining stress than single layer mesh.
