Long-term corrosion performance of epoxy-coated steel and calcium nitrite
- Grace Construction Products, Cambridge, MA (United States)
Two of the most widely used corrosion protection systems for steel in reinforced concrete are epoxy-coated steel and calcium nitrite. In severe exposures to deicing or marine environments engineers often require more than one protection system, referred to as a ``Belts and Suspenders`` approach. In this work the performances of calcium nitrite and epoxy-coated reinforcing bars in combination and alone are documented after several years of accelerated testing in good quality concretes. The data show that calcium nitrite definitely improves the performance of epoxy-coated reinforcing bars, even when they are severely damaged as might occur due to poor handling or concrete placement. Undamaged epoxy-coated reinforcing bars had similar performance to calcium nitrite and the combination system was an improvement.
