• Abstract:
  Due to its economic advantages, the use of self-consolidating concrete (SCC) has ; increased rapidly in recent years. However, because SCC mixes typically have decreased ; amounts of coarse aggregate and high amounts of admixtures, industry members have ; expressed concerns that the bond of prestressing strand in SCC may be compromised. ; While the bond performance of prestressing strand in a new material such as SCC is an ; important topic requiring investigation, the results are only applicable if the research is ; completed on strands with similar bond quality as the strands used in the field. Therefore, ; the objectives of this research program were to investigate the transfer and development ; lengths of prestressing strand in SCC and also evaluate the effectiveness of two proposed ; bond tests in determining acceptable bond quality of strand.
