Abstract:
Presents observations regarding the long-term durability of dry-mixed shotcrete used in the construction of prestressed concrete tanks. In general, shotcrete performance in prestressed concrete tanks constructed over 30 years ago has been good in the aggressive freeze-thaw environment of the northeast United States. Problems that have been observed, primarily in domes, are attributed to poor construction practice, and not to a lack of inherent durability of shotcrete.
