Title: IMPACT ON ANTICIPATED SERVICE LIFE OF CHLORIDE THRESHOLDS

Abstract:The corrosion-initiation threshold for corrosion is a key parameter that controls the expected service life of a concrete structure. Different methods of establishing threshold values that consider different components of concrete mixtures can have a significant impact on anticipated service life. This impact is evaluated using typical concrete mixtures that are used in structures exposed to chloride-laden environments across the United States. The often synergistic impact of including supplementary cementing materials (SCMs) in a concrete mixture and corrosion-initiation thresholds is examined, where the reduction of diffusion values with time can lead to a greater impact that would be expected from variation in corrosion-initiation thresholds alone.
