Strengthening Brick Masonry Columns Using Ferrocement

In most parts of the Indo-Pak subcontinent, brick masonry columns and walls were mainly used in building before concrete became widely used. The lost strength of a large number of these old brick masonry buildings needs to be restored. Brick masonry column strength enhancement was researched through ferrocement confinement in order to restore old brick masonry column strength through a retrofit arrangement. There was preparation and testing of masonry column composite behavior when coated with and without 1, 2, and 3 wire mesh layers. For some cases, there was also use of a bonding agent. Test results show that the compressive strength of bare masonry columns is quite significantly enhanced through ferrocement coating application. As compared to control specimens, a failure load increase of up to 134% was shown for ferrocement specimens with 1 wire mesh layer wrapped inside. There is also improvement in stable crack growth mechanism and cracking resistance. Load carrying capacity improvement is not helped by bonding agent use, although it is effective in concrete cover spalling control.
