Chloride Migration Variability In Reinforced Concrete Highway Structures In Pennsylvania, Connor Kane Bradley
Theses and Dissertations
To assess the potential design life for reinforced concrete highway infrastructure in the Northeastern United States, the resistance to corrosion must be known. Reinforced concrete structures in both cold and marine environments are exposed to chloride, an ion with the potential to migrate through concrete and corrode steel. Chloride content can be assessed relative to the chloride migration coefficient determined at an age of 28-days using methods defined in NT Build 492. This approach is a departure from traditional rapid chloride permeability testing methods used for qualification of concrete mix designs by state departments of transportation. To investigate the impact ...
