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:

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.
