Reinforced cement concrete (RCC) as a construction material has come into use for the last one century. In India, RCC has been used extensively in the last 50-60years.During this period, we have created large number of infrastructural assets in terms of buildings, bridges, sports stadium etc., which are lifeline for the civilized society. These have been created with huge investment of resources. We cannot even dream of recreating such assets out of limited national resources. It is there more essential to maintain them in functional condition. Since, deterioration of RCC is a natural phenomenon and has started exhibiting in large number of structures, a systematic approach is needed in dealing with such problems. Identification of the causes of deterioration and consequent repair/rehabilitation strategy at optimum cost needs a scientific evaluation and solution. Concrete constructions require proper care in the form of regular maintenance If buildings remain for several years without proper attention then, various factors like water stagnation, paint peeling, plaster break- off, fungus growth, cracking of external surfaces will affect the building. Penetration of moisture into reinforced concrete components promotes corrosion process and further damages the concrete cover. It has been observed that the deterioration phenomena of RCC are not realized by majority of practicing civil engineers. As a result, the factors considered necessary for durability of RCC buildings are many times not given due importance during construction and/or during maintenance. The durability provisions have been given emphasis in the revised Code of Practice on Plain and Reinforced Concrete' (IS: 456-2000). In the international scenario also, deterioration of CC had been drawing attention of the practicing civil engineers for quite some time. They have accordingly, made certain advancement in the field of protection, repairs, rehabilitation, strengthening and retrofitting of the existing RCC structures taking advantage of the advancement in the materials science, more particularly the polymer science. The knowledgeas UPV, rebound hammer, pH, carbonation, corrosion test, delamination, and cover metre tests were undertaken.
