Abstract:

Construction of the South Slough (Charleston) Bridge was completed in March of 1991. The structure was constructed with prestressed concrete beams using grit-impregnated, epoxy coated prestressing strands. While epoxy coated reinforcing steel has been used successfully to combat corrosion for several years, epoxy coating for prestressing strands is a relatively new application. The use of epoxy coated strands did not cause any significant construction problems. The strands and concrete mix were bonded well. The bonding characteristics of the grit-impregnated epoxy prestressed strands to the concrete will be monitored for two years, until March 1993, to detect any loss in bonding.
