Durability Evaluation of Ternary Mix Designs for Extremely Aggressive Exposures Phase II

Concrete mixtures can be very durable even in very aggressive environments. Concrete permeability is one of the main factors that governs reinforced concrete durability when exposed to chloride or sulfate ions. This project seeks to determine the correlation between the concrete mixture proportions for ternary blends and surface resistivity. Correlations between the concrete mixture proportions and alternate concrete transport property indexes including the formation factor will be determined. Finally, the relationship between surface resistivity results of concrete ternary blends and concrete durability performance for areas of degradation concern in the Florida environment include reinforcing steel corrosion caused by chloride ingress and sulfate attack durability.
