Self-compacting concrete is a flowing concrete mix that is able to consolidate under its own weight and due to this fluid nature of SCC it is considered to be suitable for placing in congested reinforcement. By using SCC, it is possible to minimize hearing-related damages on the worksite that usually occurs due to vibration of concrete. Corrosion which is one of the biggest problems that causes deterioration of concrete structures and has bigger impact in coastal areas. The corrosion causes the formation of rust which is four times the volume of original steel and does not have any of its good mechanical qualities, it also causes the loss of bond between concrete and steel which results in delamination, cracking and spalling. Corrosion inhibitor can be used to reduce the rate of corrosion when used in proper proportion by applying on the surface of steel or by adding during the preparation of concrete mix. Corrosion inhibitors are classified such as Organic and Inorganic and can also be classified on the basis of electrode reaction they possess such as anodic, cathodic or mixed inhibitors. The objective of this work is to study the behaviour of Organic and Inorganic corrosion inhibitors for steel in self-compacting concrete. The effectiveness of the inhibitors will be compared and analysed.
