Abstract:
California's new Carquinez Suspension Bridge, the first major new suspension bridge in the U.S. in over 30 years, is being built with cast-in-place concrete towers, mass concrete footings, and mass concrete anchorage for the cables. Ten different concrete mixture proportions were used in construction of the major concrete components of the suspension bridge to meet unique concrete material needs for both design and construction. The mixtures included: a lightweight, a fiber-reinforced concrete, a delayed set mixture for tremmie placements, a higher strength concrete, and mixture for mass concrete.
