CORROSION INHIBITED
The refurbishment of the Peney Bridge near Geneva, Switzerland, is described. The bridge, a 5 span, 175m long continuous double beam structure, had a number of problems relating to its design in 1942. Defects including poorly-compacted concrete, cracking and chloride penetration had resulted in more than half of the steel reinforcement being unprotected from corrosion. A corrosion inhibitor treatment, the MFP system, was chosen to provide corrosion protection in the sound but unprotective areas. Conventional repairs were then carried out to the physically defective areas. The MFP system involves the impregnation of an aqueous solution of sodium monofluorophosphate to the reinforcement level. This also reacts with the concrete, improving durability.
