Physical Responses to the Interaction of Deicer and Natural Microfines

The interactions of natural microfines and potassium acetate deicer were investigated in laboratory specimens. Microfines (material smaller than 75 µm [0.003 in.]) from five aggregate sources from locations across the western United States were characterized and subsequently studied when subjected to deicer solution while in concrete. Expansion and freezing-and-thawing durability test specimens were monitored and evaluated for damage. Based on the incurred failures and mineralogy type, the microfines were assessed. Among the microfines tested, those incorporating phylosilicates showed the greatest degradation of concrete when subjected to potassium acetate deicer over the duration of the study.
