A Rapid Test to Screen the Functionality of Galvanic Anodes for Cathodic Protection of Reinforced Concrete

Galvanic anodes are increasingly popular in the repair, rehabilitation, and maintenance of reinforced concrete structures suffering from chloride-induced corrosion for added durability benefits. There is a consensus among engineers that demand will increase due to ageing infrastructure stock, climate change, option reuse which logical solution help reduce carbon emissions. New manufacturers likely emerge meet needs growing market. However, there no standard galvanic use concrete. In theory, products may come market fails work as anodes, hence not be arrested, repeated intervention could required. This paper presents methodology has been developed demonstrating function intended short-term test. Anodes were cast into concrete, drive voltage, resistivity, resultant current measured when connected an external cathode. The test setup was applied several commercially available anodes. All achieved output 0.35 mA this experimental setup. provide rapid screen new analyses show inherent anode behaviour varied with different manufacturers, also performance differences replicate Such behavioural characteristics affect long-term These results data on demonstrate potential need standardisation industry.
