Speaker: Dr George Sergi – VECTOR. Galvanic Corrosion Control of Reinforced Concrete:

Topic: Galvanic Corrosion / CP Control of Reinforced Concrete; Lessons learnt from 20 years of Site Trials. Sacrificial anodes have been used in reinforced concrete structures for up to 20 years. This presentation reviews the performance of the oldest set of anodes used in enhanced patch repairs where anodes were placed at the periphery of the patch at around 600 mm spacing on centre. It demonstrates, from results of current output and steel de-polarisation levels that the repair system is still functioning adequately. These prototype anodes, designed for a 10-year life, have continued to deliver a reduced but significant current complying with currently accepted criteria. The overall reduction in current was found to be adequately described by an ‘anode aging’ model where the current delivered is halved over constant time intervals, enabling determination of an ‘aging-factor’.
