126 3,000-pound bulk bags of Quikrete General Purpose Non-Shrink Grout and 104 3,000-pound bulk bags of Flowcrete V were used on this job

Flowcrete V, a flowable, shrinkage compensated, structural concrete, was used to fill the void between the inner and outer piles wider than 6 inches on the Bay Bridge project. It is designed as an original or repair concrete in situations that require a high-quality concrete with a maximum aggregate size of 10 millimeters. It can be mixed to any consistency – from stiff plastic to flowing and requires no mechanical vibration to consolidate the mix.

In total, crews on the Bay Bridge used 126 3,000-pound bulk bags of Quikrete General Purpose Non-Shrink Grout and 104 3,000-pound bulk bags of Flowcrete V.

When finished in 2013, the SAS is expected to be one of the largest structures of its kind in the world.
