The fresh properties for the mix, as provided by the concrete and admixture suppliers, included a 23-in.

(584-mm) spread, a J-ring value of zero, and an air content of 5.5%.

These include measurements from concrete embedment strain gages as well as foil strain gages mounted directly to the prestressing strands and caisson reinforcement.

Bridge Construction In addition to the use of SCC for the three drilled shafts, a second SCC mix was used in the construction of two of the five precast, prestressed concrete box beams that were used to construct the superstructure.

The other three box beams were constructed using a traditional vibrated concrete mix.

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.

Self-consolidating concrete (SCC) was used in the construction of three caissons for a rural bridge replacement of the Stalnaker Run Bridge in West Virginia.
