After tensioning, steel bulkheads were positioned to form
the ends of each specimen. Mild steel reinforcement and
strand shielding (specimen SL only) were then placed.
After reinforcement was placed and checked, steel forms
were oiled, placed, and squared. Concrete was mixed at an
on-site batch plant and was transported and placed using
the fabricator’s mixer truck and delivery equipment. A
self-consolidating concrete mixture was used, so vibration
was not necessary for compaction. The top surface of each
girder was troweled smooth. Girders were covered with
heavy tarps and were cured at ambient temperature.
