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.

Abstract:

In the course of performing field surveys of bridges for a bridge deck durability study, it was noted in some instances that the type of forms used to construct the decks appeared to influence deterioration and cracks. . .Observations indicate that SIP formed decks have a higher moisture content than do conventionally formed decks.
