Rust is a chemical reaction that involves the exchange of electrons between atoms; certain chemicals can accelerate rusting by increasing the electrical activity between iron and oxygen. Substances such as salts and acids increase the conductivity of moisture around metal, making rust happen more quickly.

Corrosion of Eedded Metals - Portland …

No other contaminant is documented as extensively in the literature as a cause of corrosion of metals in concrete than chloride ions. The mechanism by which chlorides promote corrosion is not entirely understood, but the most popular theory is that chloride ions penetrate the protective oxide film easier than do other ions, leaving the steel vulnerable to corrosion.
