The corrosion of steel leads to failure or needs demolition of structures. Cathodic protection technology is well proven for corrosion protection of steel and in 2020 this technology will complete its 200 years of existence. For RCC buildings cathodic protection technology is not common due to several reasons. The lack of awareness in public about the fact that maintenance is only cosmetic repair and it does not ensure the protection of steel from corrosion. The sacrificial anode CP system is well suited for buildings since the requirement of anode material will always be less in case of buildings. To make it popular a new system of SACP is developed and it is named as Sacrificial Surface Anode Cathodic Protection (SSACP) system. The device is designed as external, it is easy in installation, replacement and monitoring. It is reliable, economical and does not damage the aesthetic appearance of building. The present research is about onsite corrosion prevention of steel using Sacrificial Surface Anode. For evaluation of performance a number of SSA are installed in one of the multi-story buildings in Surat city about 18 km from sea shore. This includes the working of SSA which depends upon the resistivity and moisture content of concrete cover to reinforcement. Index Terms: Cathodic Protection, Sacrificial Surface Anode, Resistivity of Concrete, and Conductivity of concrete. I. INTRODUCTION The structures built before the innovation of modern cements used the lime as binding material and stone, bricks or timber were used for making structural elements. The raw materials used for production of cement are oxides of calcium carbonate and silica in majority so it is assumed that the concrete made by using today’s modern cement will have a useful life more than 100 year. Similarly, it is assumed that the steel will have a useful life much more than concrete if protected and proper metallurgical composition is designed Revised Manuscript Received on July 05, 2019.

Vesmawala, Associate Professor, Department of Applied Mechanics, Sardar Vallabhbhai National Institute of Technology, Surat, India With the advancements in technology of cement and steel world became more confident that any structure made of reinforced cement concrete will have a life span of more than 100 years. In the race of development, we forgot the law of conservation of energy which is responsible for changing one form of material to another form. The cycle time may be few hours to thousand years.All materials natural, artificial or composite require proper storage or maintenance. The experience of last fifty years shows that the structures built with cement and steel available in seventies are still better compared to structures built in nineties. The reasons are lower grade of cement, low rise buildings, higher factor of safety lowering the actual stresses, and less number of structures to look after by the concerned agencies. Still many reasons are there we have put only few for attention of readers. The present average life of RCC buildings in India in coastal areas is about 30 to 60 years depending upon a number of factors. The major cause is corrosion of reinforcement and further reduction of strength of structure. The various techniques in practice, to minimize or to stop the corrosion, are Metallurgical Methods, Corrosion Inhibitors, Coating to Reinforcements, Coating to Concrete, Design and Detailing and Cathodic Protection. The metallurgical method, corrosion inhibitors, coating to reinforcement, design and detailing are the methods of corrosion protection which can be applied before or during construction. The coating to concrete is a method which delays the corrosion but for existing structure in which already corrosion has started or to stop initiation of corrosion the only method is cathodic protection. II. HISTORY OF CATHODIC PROTECTION The history of cathodic protection may be very old but the first cathodic protection was investigated in 1820 by Sir Humphrey Davy. He used small quantities of zinc and iron for protecting the copper sheeting. The terminology used by him was cathodically protected. In 1834 he discovered the relation between corrosion weight loss and electric current which laid the foundation for future application of cathodic protection. After about 100 years of Davy’s research cathodic protection was widely adopted as corrosion protection method. In US the cathodic protection was adopted for protection of thin walled pipe line used for transmission of oil and natural gas. Till 1945 this method was well established in United States.in 1959 Richard Jaiprakash B. Sharma, Yogesh D. Patil, Gaurang R.
