Test Protocol Evaluates Concrete Repair with Sacrificial Anodes

摘要

One of the most common drivers of concrete repairs is corrosion of the concrete's steel reinforcement. This type of corrosion is often caused by chloride ions in the environment entering the concrete and eventually reaching the embedded steel. When the build-up of chloride ions at the steel reaches a certain concentration, and moisture and oxygen are present at the concrete/steel interface, the steel's passive oxide layer will break down and corrosion can initiate.
