Evaluation of self consolidating concrete for bridge structure applications

The Stalnaker Run Bridge is located on Old Route 219 in Elkins, WV.SCC was used to cast elements of both the substructure and the superstructure of the single-span bridge, with traditional vibrated concrete being used to cast identical elements in the same bridge for purposes of comparison.Another advantage of SCC is that the time required to place large sections is considerably reduced.When the construction industry in Japan experienced a decline in the availability of skilled labour in the 1980s, a need was felt for a concrete that could overcome the problems of defective workmanship.It is noted that although blending of more than one type of aggregate was permitted by the project specifications, the final mix design used only No.67 aggregates for the sake of simplicity, but including an aggregate blend could help optimize the performance.Both sets of caissons were cast successfully, and they eventually became integral parts of their respective bridge abutments.No noticeable defects were detected within the cages of any of the six caissons by cross-hole sonic logging (CSL) when tested 5 or more days after casting.

In Japan, the volume of SCC in construction has risen steadily over the years.To restore access and understand how to better interact with our site to avoid this in the future, please have your system administrator contact [email protected] Developments in Self-Compacting Concrete Introduction Self-compacting concrete (SCC) is a flowing concrete mixture that is able to consolidate under its own weight.This is not an indication of a security issue such as a virus or attack.It could be something as simple as a run away script or learning how to better use E-utilities, for more efficient work such that your work does not impact the ability of other researchers to also use our site.
