Electrochemical re-alkalisation is increasingly popular as a means of rehabilitating carbonated reinforced concrete in which the steel is at risk of corrosion. In addition to repassivating the steel, passage of electric current and the associated migration of electrolyte solution could change the properties of the concrete. The evidence available suggests that the risks of potentially harmaful side effects on the mechanical properties and pore structure of the concrete have been exaggerated. However, further confirmation that there are no adverse effects on alkali-silica reactivity and durability is still required.
