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:

A survey of 249 four-year old Pennsylvania bridge decks was conducted for two purposes: To determine the condition of the decks with regard to the extent and severity of their deterioration, and to provide insight into the relative importance of those factors, or combination of factors, which cause deterioration.

Abstract:

SP47 Presents a collection of 17 papers on freeze-thaw problems, performance of concrete in seawater, and sulfate attack, to help advance understanding of the response of concrete to attack by aggressive elements. Knowledge of the mechanism, the development of a course of action, and a report of the field experience are all necessary contributions to improving our knowledge of concrete durability. SuccessfuI performance of concrete is dependent to a greater extent on its durability against the environment than on strength properties.

Abstract:

The 6 Missouri River dams constructed by the Corps of Engineers are in a region where the ground water has a high sulfate content. The concentration is highest at Ft. Peck, Oahe, and Big Bend. The problem was recognized at the time of construction of Ft. Peck Dam in the mid-30s, and this is perhaps the first major project in the U.S. where a sulfate reistant cement was specified. . .An up-to-date evaluation of the condition of the Ft. Peck concrete is advisable.

Abstract:

The results of a test program are reported in which uniaxially restrained, air-entrained concrete prisms made with shrinkage-compensating Types P, M, and S cements were immersed in sulfate solutions after 14 days of water curing.
