Evaluation of Silica Fume in Bridge Deck Concrete Overlays

In 1990 two silica fume bridge deck overlays were placed on I-470 in Shawnee County along side of two control bridges. While the silica fume overlays have successfully inhibited the chloride penetration of the concrete, extensive cracking occurred in the silica fume overlays.

Silica Fume Applications in Concrete

High-strength concrete enhanced with silica fume provides architects and engineers with greater design flexibility. Traditionally used in high-rise buildings for the benefit of smaller columns (increasing usable space) high-strength concrete containing silica fume is often used in precast and prestressed girders allowing longer spans in structural bridge designs.
