“…The uniform distribution of reinforcement in mortar improves many engineering properties such as the ductility, crack resistance, in-plane strength and durability. Ho et al [7] strengthened circular plain and RC columns with high performance ferrocement jackets (comprising rendering material and wire mesh). Yaqub et al [8] tested post-heated square and circular RC columns after repair with ferrocement jackets.…”

“…The more availability, lower cost and less need for advanced installation technique for steel meshes (EMM and WWM) make them predominant in developing countries. Steel meshes encapsulated in thin-wall mortar layer (ferrocement, [6]) were extensively used in repair and rehabilitation of existing concrete columns [2,3,[7][8][9][10][11]. The uniform distribution of reinforcement in mortar improves many engineering properties such as the ductility, crack resistance, in-plane strength and durability.…”

Traditional steel ties reinforcement cannot provide superior confinement for reinforced concrete (RC) columns due to the constraints on tie spacing and disturbance of concrete continuity. This paper presents a practical confinement configuration consisting of single Expanded Metal Mesh (EMM) layer in additional to regular tie reinforcement. The EMM layer is warped above ties. The proposed transverse reinforcement, with various volumetric ratios of ties, was investigated in sixteen square short RC column specimens categorized in two groups according to their slenderness ratios. The specimens were cast in vertical position simulating the construction field and they were tested under concentric compression till failure. The results indicated that the columns, confined with proposed lateral reinforcement, revealed significant improvement in the strength and ductility. Also, high reduction in ties volumetric ratio with no loss in ultimate load could be achieved by installing the EMM layer.

This paper presents results of an experimental study on the increase in the load carrying capacity of conventional ferrocement wrapped columns and modified ferrocement columns. In this study a ferrocement wrapping reinforced with 2 layers of welded steel meshes is used. Six short RCC square columns including four strengthened columns (Two with conventional ferrocement and two with modified ferrocement) were tested. The specimen were subjected to axial compressive load till failure. The results indicated that the increase in load carrying capacity of Column wrapped with conventional ferrocement is about 79.60% over control specimen that of column wrapped with modified ferrocement is about 89.80% over control specimen. Hence it is concluded that modified ferrocement jackets can be effectively used for strengthening of columns.

Ferro cement is a type of thin wall reinforced concrete commonly constructed of hydraulic cement mortar reinforced with closely spaced layers of continuous and relatively small size wire mesh. The mesh may be made of metallic or other suitable materials. The fineness of the mortar matrix and its composition should be compatible with the mesh and armature systems it is meant to encapsulate. The matrix may contain discontinuous fibers. The results of an experimental study on the increase in the load carrying capacity of modified ferro cement wrapped columns and Carbon Fiber Reinforced Polymer sheet wrapped columns. The modified ferro cement wrapping reinforced with 2 layers of welded steel meshes is used. Six short RCC square columns including four strengthened columns (Two with modified ferro cement and two with2 layers of CFRP) were tested. The specimens were subjected to axial compressive load till failure. The results indicated that the increase in load carrying capacity of Column wrapped with modified ferrocement is about 89.80% over control specimen and that of column wrapped with CFRP sheet is about 74.28% over control V Anandan, S Senthamilkumar, V Sundararajulu, S Gunaselvi and M Jeganathan http://www.iaeme.com/IJARET/index.asp 42 editor@iaeme.comspecimen.
