Case study of Ramagundam Fertilizers and Chemicals Limited – Corrosion Inhibiting Admixture

Ramagundam Fertilizers and Chemicals Project:

Telangana’s Ramagundam Fertilizers and Chemicals Project is one of India’s largest fertiliser plants.

RFCL is a joint venture between National Fertilisers Limited (NFL), Engineers India Limited (EIL), and Fertilizer Corporation of India Limited (FCIL). The gas-based plant can churn out 1.27 million tonnes of urea annually.

To ensure the longevity and durability of the plant structure, the contractors sought a reliable corrosion inhibiting admixture to be added to the concrete mix.

Application for Ramagundam Fertilizers and Chemicals Project:

Sunanda Global provided the contractors with ‘Sunanda Corrosion Inhibiting Admixture’ for the above project. It is a chloride-free, water-soluble admixture that contains organic and inorganic inhibitors that offer long-lasting protection against corrosion. 

The admixture is designed to reduce concrete penetration and protect the steel reinforcements from corrosion caused by chlorides, carbonation, and other aggressive agents.

Sunanda Global’s corrosion inhibiting admixture resulted in several benefits, including improved durability, longevity, reduction in maintenance costs, and environmentally friendly concrete structure solutions.


The integration of Sunanda Global’s Corrosion Inhibiting Admixture into the construction specifications of the Ramagundam Fertilizers and Chemicals Project has proven to be a pivotal decision.

This chloride-free, water-soluble admixture, enriched with inhibitors, has effectively shielded the plant’s concrete structure from the detrimental effects of corrosion.

With the ability to mitigate the impact of aggressive agents such as chlorides and carbonation, this innovative solution not only enhances the durability and longevity of the infrastructure but also contributes to a significant reduction in maintenance costs over the plant’s operational lifespan.

The success of Sunanda Global’s corrosion inhibiting admixture in this project highlights its pivotal role in safeguarding the steel reinforcements within the concrete, ultimately ensuring the sustained structural integrity of one of India’s largest fertilizer plants.

Beyond the tangible benefits of improved structural resilience and longevity, the environmentally friendly nature of this solution aligns with contemporary sustainability goals.

It sets a precedent for future construction projects seeking reliable corrosion protection solutions.

In essence, the incorporation of this cutting-edge admixture has not only met but exceeded the project’s expectations, underscoring its significance in fostering sustainable and resilient infrastructure for years to come.
