• Abstract:
  The objective of this study was to determine the influence of admixtures on long term drying shrinkage and creep of high ; strength concrete (HSC). Creep and shrinkage of the mix utilized in segments of the Skyway Structure of the San ; Francisco-Oakland Bay Bridge was also monitored. ; Cement paste alone was investigated to remove the effect of aggregate on shrinkage as to the effect of individual ; admixtures on drying shrinkage of HSC. ; This study reveals that the type and amount of admixture are key factors that can affect the drying shrinkage, creep and ; compressive strength. The mixtures used showed that most of the drying shrinkage occurs during the first 100 days after ; mixing.
