CAC®-CORROBIT OCI Plus | Bipolar Corrosion Inhibitor for Reinforced Concrete

CAC®-CORROBIT OCI Plus | Extending the Life of Critical Infrastructure

#Corrosion is one of the leading causes of premature deterioration in critical infrastructure. It increases repair costs while compromising public safety, sustainability, and structural performance.

According to a recent Nomura report, India loses approximately ₹14 lakh crore annually, equivalent to 4.3% of its GDP, due to corrosion-induced damages. The infrastructure sector alone incurs losses of around ₹1.42 lakh crore, or 2.9% of GDP each year. The report further highlights that improving corrosion protection practices could increase India’s GDP by up to 1.5%.

Bridges, buildings and other critical infrastructure in corrosion-prone areas are continuously exposed to moisture and contaminants, which accelerate the corrosion of reinforcing steel, making effective corrosion protection critical to improving durability and extending service life.

How can we better protect reinforced concrete infrastructure and build for a more sustainable future?

CAC®-CORROBIT OCI Plus is a bipolar corrosion inhibitor designed to protect reinforcing steel in concrete from corrosion, helping improve the durability and service life of reinforced concrete structures.

Its adsorption-based mechanism forms a protective layer around reinforcing steel, delivering the following benefits:

✔ Increases the chloride threshold value by approximately 3.5 times
✔ Reduces the corrosion rate by approximately 70%
✔ Protects reinforcing steel against chloride-induced corrosion
✔ Inhibits both anodic and cathodic corrosion reactions
✔ Helps extend the service life of concrete by approximately 2.7 times

Extensive research conducted at IIT Madras demonstrated that concrete incorporating CAC®-CORROBIT OCI Plus achieved a longer service life under chloride exposure than conventional concrete.

At #CAC, we continue to develop innovative concrete protection solutions that help reduce maintenance, improve lifecycle performance, and support safer, more sustainable infrastructure.
