• Abstract:
  Based on the study presented in this report, it was determined that S50 structural concrete can be produced to meet the requirements of the CDOT Standard Specification for Road and Bridge Construction, Section 601. S50 mixes using cement as well as cement/fly ash blends can be successfully produced with the aid of proper high-range water-reducing (HRWR) admixtures. The low w/cm ratios used in this study allow the development of a high-strength structural concrete and low drying shrinkage, while retaining air content between 5% and 8% for freeze/thaw durability.
