Study on Application of Blast-furnace Slag Cement Concrete to PC Girders Based on Evaluation of Shrinkage and Creep

摘要

The application of blast-furnace slag cement concrete (BC) to PC girders is one good method to prevent ASR; however, its shrinkage and creep have not been evaluated. This paper summarizes the result of the compression creep tests executed, and shows that the shrinkage and creep of BC can be evaluated through conventional equations, usually used for normal cement concrete (NC). In addition, the analysis results indicate that even if BC is applied, the deflection and prestress loss of PC girder differ only a little from that of NC.
