Abstract:

There are limited measurements documented in the literature related to long-term prestress losses in self consolidated concrete ; (SCC) members. Recorded test data has shown variations in mechanical property behavior of SCC compared to conventional ; HSC mixtures in the 8-12 ksi range. Over the past year, precast manufacturers such as Coreslab Structures, Inc., in Marshall, MO ; have experienced inconsistencies in camber behavior with SCC which may be attributed to mechanical property variations, but ; variation in stress may also be a contributing factor. Additionally, increasing the allowable fiber stress limit is desired for full ; utilization of materials and members, as long as structural performance is maintained. Furthermore, accurate prediction of time-dependant ; prestress losses is essential for determination of the effective prestress force, which effects serviceability prediction and ; structural perfromance. Further investigation is required.
