GALVANIC CATHODIC PROTECTION OF STEEL IN CONCRETE METALNASTRI ANTICORROSION SYSTEMS

Corrosion is recognized as one of the major contributors to the deterioration of reinforced and pre-stressed concrete structures worldwide. The amount of reinforced concrete structures world-wide is growing rapidly and therefore so is the increasing necessity of easily applied low-cost maintenance programs. Over the last 30 years, cathodic protection (CP) has been shown to be a highly effective technique in preventing concrete deterioration from chloride induced and carbonated concrete corrosion. The presence of chloride based salts within the concrete can be a threat to the passivation layer...
