Title: A method for Predicting Sulfate Durability of Concrete
Author(s): Carl D. Harmann and Edward Mangotich
Publication: Special Publication

Abstract:A laboratory study was conducted to evaluate the effect of replacement of up to 35 percent by weight of the design cement content in a concrete mix with Class C fly ash on sulfate durability characteristics. Seven trial batches, including a control, one Class F, and five Class C ash mixes, and three types of test specimens were used. The test sulfate environment consisted of immersion in a 10 percent pH regulated sodium sulfate solution for more than two years. Weekly measurements of weight change and expansion were used to evaluate sulfate durability. Analyses of the expansion data suggest a calculated chemical compositional relationship called the oxide durability factor may be useful in predicting sulfate durability.
