WHAT IS CORROSION PREVENTION?
Corrosion Prevention of reinforced concrete structures is an increasingly important method of repairing and protecting damaged bridges, buildings, wharves and other structures. It can also be applied to protect new structures to ensure corrosion does not occur in the first place. Corrosion is probably the single most serious cause of deterioration of reinforced concrete structures. Buildings and bridges are suffering from corrosion because of contamination by de-icing salt, sea salt and salts cast into the concrete. A Dept of Transport report has shown that over half a billion pounds worth of corrosion prevention is necessary in the future to preserve the motorway and trunk road system in England and Wales. The Highways Agency has recently endorsed the use of corrosion prevention methods utilising cathodic protection, realkalisation, chloride extraction and other similar techniques. Comparable problems exist on other reinforced concrete structures all over the world. These well proven
