Reinforced concrete has a high compressive strength compared to other building materials. R.C.C. is a versatile construction material which is strong in compression as well as tension. The use of reinforcement in concrete not only increases its strength but also helps in preventing the temperature and shrinkage stresses. The premature deterioration of structure is an economic burden not only on owners but also to the municipalities’ and Nation as a whole. The longer life of structures enables better utilization of natural resources. There are several problems that RCC structural members experience and needed to be tackled. Over a period, as these structures become older, we find in them certain degradation or deterioration with resultant distress manifested in the form of cracking, splitting, delaminating, corrosion etc. Such deteriorated structures can be rehabilitated and retrofitted by using various types of admixtures & modern repair materials. The paper brings out the major areas where improvement is needed during its service life and different methods of retrofitting.
