摘要：	This paper summarizes the work conducted by the Virginia Department of Transportation on self-consolidating concrete (SCC). Initially, a laboratory study with locally available materials was conducted to develop and evaluate the properties of SCC, including flow, segregation, strength, permeability, resistance to cycles of freezing and thawing, and drying shrinkage. Studies at two precast plants followed. Then, one of the precast plants furnished SCC for an arch bridge. The other plant fabricated two bulb T-beams with SCC. Studies also were conducted with cast-in-place SCC. A structures pad at the FHWA Turner-Fairbank Highway Research Center, a median on I-64, and a column in Norfolk, Virginia, were constructed with SCC. The results show that SCC can be produced successfully and provide many benefits to transportation agencies and the construction industry.
