COMPARATIVE STUDY ON THE BEHAVIOR OF CONVENTIONAL FERROCEMENT AND MODIFIED FERROCEMENT WRAPPED COLUMNS

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 convensional 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
