Case Studies of Rehabilitation/Repair of Reinforced Concrete Structures

Abstract

Concrete constructions and structures require proper care in the form of regular and proper maintenance. If buildings remain for several years without proper attention and poor caring then, then various factors causes like water stagnation, paint peeling, plaster break-off, fungus growth, cracking of external surfaces resulting its affect the building. Penetration of moisture into reinforced concrete components arises corrosion process and further damages the concrete cover and member. It has been observed that the deterioration phenomena of RCC are not realized by majority of practicing or less experience 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. In the international scenario also, deterioration of RCC structure had been gaining attention of the practicing civil engineers for quite some time. They have accordingly, made certain up gradation in the field of protection, repairs, rehabilitation, strengthening and retrofitting of the existing RCC structures.
