DURABILITY GAINING IN AN OLD STRUCTURE USING RETROFITTING TECHNIQUES

Retrofitting' of a structure mainly deals with the addition of updated technology in an old structure to improve the strength and durability of the structure. This study deals with the adoption of new retrofitting techniques, methodologies and ideas to improve the life time of the old buildings in an efficient way. Fiber wrapping is the technique discussed in this study. By adopting this we can overcome external cracks in concrete and masonry structures. e-glass fiber or carbon fiber is used for this technique. Epoxy chemical is used for strong setting of fibers into the structure. In this study compression strengths are identified for both ordinary concrete cubes and also fiber wrapped concrete cubes and identified the percentage of strength improvement
