Abstracts: • Concrete construction is generally expected to give trouble free service throughout its intended design life. However, these expectations are not realized in many constructions because of structural deficiency, material deterioration over loading or physical damage. Premature material deterioration can arise from number of causes. This damage needs appropriate methods of repair. • Concrete constructions require proper care in the form of regular maintenance. Water stagnation, paint peeling, plaster break off, fungus growth, cracking of concrete are common. Penetration of moisture into reinforced concrete components promotes corrosion process and further damages the concrete cover.
