Protecting Concrete with Cortec® MCI® Admixtures: Advanced Corrosion Inhibition

Cortec® MCI® (Migrating Corrosion Inhibitor) concrete admixtures offer an innovative solution for enhancing the durability of concrete structures. Designed with cutting-edge amine technology, including amine alcohols and amine carboxylates, MCI® admixtures provide superior corrosion protection by targeting both anodic and cathodic areas of a corrosion cell.

The unique vapor-phase mechanism of MCI® admixtures sets them apart. This allows the corrosion inhibitors to migrate into areas adjacent to the application site, forming a protective layer on metal surfaces and extending coverage beyond direct contact. This advanced feature is particularly beneficial for protecting embedded reinforcement in concrete structures exposed to harsh environments.

Key Benefits of MCI® Admixtures

  1. Environmental Responsibility
    Unlike traditional calcium nitrite-based inhibitors, Cortec® MCI® admixtures have lower toxicity and a reduced environmental footprint. Biobased components, such as amine carboxylates derived from renewable corn sources, make these admixtures a sustainable choice for construction projects.
  2. Lower Dosage Rates
    MCI® admixtures are cost-effective, requiring significantly lower dosage rates than competitors. While traditional solutions often require gallons, MCI® admixtures are effective in pints, offering both economic and logistical advantages.
  3. Versatility and Performance
    With dosage rates that remain effective regardless of chloride levels, MCI® admixtures are versatile and adaptable to various environments. Additionally, they maintain minimal impact on concrete mix properties, preserving workability, strength, and air entrainment.
  4. Migration Through Porous Substrates
    These admixtures exhibit exceptional ability to penetrate porous materials, such as concrete, masonry, and limestone. Utilising capillary action, vapor diffusion, and ionic attraction, MCI® admixtures extend protection even to areas that are difficult to reach.

Cortec® MCI® admixtures provide a non-set-accelerating solution to safeguarding concrete infrastructure. From reducing maintenance costs to prolonging structural life, their innovative formulation makes them a standout choice for corrosion protection. By combining sustainability with performance, MCI® admixtures reinforce Cortec’s commitment to environmentally friendly, high-performing construction solutions.
