• Description:
  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.
