• Abstract:
  The objectives of the study were to identify PCC mixes that offer increased deicer-freeze-thaw durability and to identify mix characteristics that contribute to premature durability distress. PCC mixes covering a range of air contents and water-cement ratios were mixed in the Wisconsin Dept. of Transportation (WisDOT) Central Oddice laboratories and evaluated at the University of Wisconsin-Madison. Evaluation included measurement of dimensional change, weight loss and dynamic modulus of elasticity during a regime of accelerated freeze-thaw cycling in a sodium chloride/calcium sulfate solution. Petrographic examination was conducted on specimens of each mix following the freeze-thaw testing. the study did not succeed in producing concrete specimens that mimicked the deicer distress found in certain Wisconsin pavements. The study did establish that higher cement contents and resulting low eater-cement ratios offer considerable additional protection for deicer-freeze-thaw exposure and more protection than simply increasing air content alone. Lowering overall san content appeared to also improve deicer-freeze-thaw durability compared to otherwise similar mixes and cement content.
