Title: Deicer Scaling Mechanisms in Concrete
Author(s): Frederick P. Browne and Philip D. Cady
Publication: Special Publication
Appears on pages(s): 101-120
Keywords: absorption; calcium chlorides; chemical attack; concretes; deicers; deterioration; freeze-thaw durability; ice formation; pore water pressure; scaling; sodium chloride; tensile strength; thermal expansion; water-cement ratio
Abstract:Three experiments were conducted to study the characteristics of the two primary deicer scaling mechanisms in concrete: 1) a hydraulic pressure mechanism, which is strongly dependent upon the degree of saturation and the deiceer gradient, and only occurs under freeze-thaw conditions, and 2) a chemical mechanism, which operates between concrete and concentrated calcium chloride solutions. These two mechansims are completely independent of one another.
