Calcium nitrite is a key ingredient for enhancing the durability of concrete structures, especially those exposed to harsh environments like deicing salts or seawater. TradeMark Nitrogen’s C-Nite® 30% Solution is a trusted product addressing these challenges—engineered to protect steel rebar by forming a protective, passivating film that minimizes corrosion.
What Is Calcium Nitrite?
Calcium nitrite (Ca(NO2)2) acts as a corrosion inhibitor in concrete. When mixed into fresh concrete, it interacts with steel rebar to block the chemical reactions that cause rust. This passivation means longer-lasting structures and fewer costly repairs over a building’s lifetime.
Why Choose C-Nite®?
C-Nite®, TradeMark Nitrogen’s branded 30% calcium nitrite solution, delivers multiple advantages:
- Improved Durability: Reinforced concrete treated with C-Nite® remains resilient when exposed to corrosive elements—ideal for bridges, parking decks, and marine structures.
- Cost Savings: Initial investment pays off by reducing long-term maintenance, extending the useful life of infrastructure.
- Environmental & Sustainability Benefits: Structures stay operational longer, using fewer resources for repairs or replacements.
