Galvanic Anodes in Patch Repairs: When Sacrificial Protection Prevents Ring-Anode Spalls

Introduction Galvanic anodes in patch repairs are sacrificial metal pieces placed near the patch to protect embedded steel from corrosion. They work by attracting corrosion to themselves rather than the steel, helping prevent ring-anode spalls. Use this approach when you want durable repairs and want to minimize crumble around the patch. Spalling is when concrete
