Silica Fume for Concrete Bridge Decks

摘要

Placing and consolidating con- crete containing silica fume is essentially the same as for concrete without silica fume. Because silica fume eliminates bleed water in concrete, finishing silica-fume concrete for bridge decks and other flatwork usually is done without the bleed water waiting periods associated with traditional finishing practices. Curing must begin immediately after finishing to protect the concrete from drying.
