Creep and shrinkage can be critical factors for design of structural members due to the length change by time dependent deformation. In this paper, four high strength self-consolidation concrete specimens (HS-SCC) and other four normal strength self-consolidation specimens (NS-SCC) were developed and tested to measured creep and shrinkage for each mixture. The samples of these mixtures were taken from a multiple-spans Bridge A7957- Route 50 in Osage County, Missouri, USA where construction has been completed. Span No. two of the bridge was cast with HS-SCC and span No. three with NS-SCC. The specimens were beam cured (Steam cured) at 120 °F (49 °C). This study shows that HS-SCC developed 13% higher creep at 120 days than NS-SCC and also HS-SCC exhibited 12% higher drying shrinkage at 180 days than NS-SCC. The results of this study were compared to different prediction models used to predict creep and shrinkage. Correction factors are presented to account for adequate prediction of creep and shrinkage for HS-SCC and NS-SCC.
