Why CT-70® Calcium Nitrate Matters in Concrete
Today's concrete industry demands more than strength alone—it requires long-term durability and reliable performance. TradeMark Nitrogen's CT-70® calcium nitrate solution is a proven concrete additive that helps improve corrosion protection, accelerates set times, and enhances overall concrete quality.
Widely used in reinforced concrete applications, CT-70® is an excellent choice for ready-mix producers, DOT projects, precast manufacturers, and other demanding construction environments.
Corrosion Protection for Reinforced Concrete
Corrosion of embedded reinforcing steel is one of the leading causes of concrete deterioration, particularly in structures exposed to chlorides such as road salts or marine environments.
CT-70® helps protect reinforcing steel by:
- Promoting formation of a protective oxide layer on steel reinforcement
- Reducing the impact of chloride ions
- Increasing the threshold for corrosion initiation
Result: Longer service life, improved structural durability, and reduced maintenance costs.
Improved Set Time and Early Strength
CT-70® also functions as an effective set accelerator, especially during cooler weather conditions.
Benefits include:
- Faster set times
- Improved early compressive strength
- Greater productivity for precast operations
- Support for fast-track construction schedules
Enhanced Workability and Concrete Quality
When properly dosed, CT-70® improves cement hydration efficiency, promotes more uniform curing, and helps reduce early-age cracking.
Unlike chloride-based accelerators, CT-70® delivers these performance benefits without increasing the risk of reinforcing steel corrosion.
Applications Across the Concrete Industry
CT-70® is used in a wide range of concrete applications where durability and corrosion resistance are essential, including:
- Department of Transportation (DOT) projects
- Bridges and highways
- Wastewater treatment structures
- Precast concrete products
- Marine and coastal construction
- Commercial and industrial concrete projects
