Case Studies of Rehabilitation of Existing Reinforced Concrete Structure

The building material mainly reinforced concrete is being used comprehensively for innumerable forms of construction developments. Although reinforced concrete structures are designed as per codes / standards but enough care is not always taken during construction process. The various causes of structural failure and the principles of rehabilitation of structures are discussed. To one side, it requires regular maintenance and on other side many structures call for widespread repair, rehabilitation & retrofitting. With the passage of time, as these structures develop older, we discover in them certain dilapidation or weakening with subsequent distress revealed in the form of delamination, cracking, corrosion and splitting etc. Such worsened structures can be repaired, rehabilitated and retrofitted by means of several sorts of admixtures & new repair materials. The main criteria is how to repair a reinforced concrete elements of structures and for this the skills, knowledge, and experience required to repair damaged or deteriorated structures are decidedly different from those required to build new structures. The purpose of this project is to suggest methods of repair, rehabilitation and retrofitting of RC framed structures and to justify the latest techniques, advanced materials and various requirements of repairing work to obstruct the deterioration which is necessary and economical than to reconstruct the building.
