Since last few years, the demand of strengthening is going on increasing due to variety of reasons. The various reasons for deterioration of structural members include change in loading condition, improper design or execution, change of functionality of building etc. Construction of new structure post demolishing old one will not only be uneconomical but also it might have adverse effect on the adjoining structures. Thus, it is not advisable. Rather it is better to enhance the load bearing capacity of the present deteriorating structure. Beams are the most important members of any structure. They are designed for flexure and checked for shear. However, the flexural failure of beam is preferred against the shear failure which lead to catastrophic failure. Various materials are now available in the market for strengthening of RC Beams. A study has been carried out wherein 5 beams were casted of 2000 mm length, 200 mm width & 270 mm depth followed by testing after strengthening. In the current experiment, materials used for strengthening are weaved mesh and welded mesh, using mechanism of Ferro-cement & Micro-Concrete. Further loads and deflections were measured and the results show improvement in load carrying capacity of strengthened beam as compared to non-strengthened beam.

Keywords- Shear, Strengthening, Ferro - cement, Micro-Concrete, weaved mesh, welded mesh.
