Corrosion of reinforcements has been one of the major challenges that the civil engineers have been facing. Corrosion leads to the formation of rust which results in the spalling of concrete which in turn leads to the exposure of rebars to the aggressive environment. This will accelerate the ill effects and ultimately leads to the break down of the structure. Corrosion mainly occurs in areas of aggressive environment such as coastal regions. It is very important that corrosion of reinforcement must be prevented in order to have a durable structure. Even though there are many methods to prevent corrosion, most of them are uneconomical and requires great skill. Some of the recent studies in various parts of the world have revealed that High Volume Fly Ash (HVFA) concrete can protect the steel reinforcement more efficiently, so that it can resist corrosion, and thus the structure as a whole. HVFA concrete is a type of concrete in which a part of the cement is replaced by fly ash, which is an industrial waste. Thus the implementation of H V F A concrete can minimize corrosion in an effective way. Moreover it can lead to much durable structure without considerable increase in cost.
